Uni -T UT383BT Lux meter
www.uni-trend....
I test the newest version of the PPFD meter app for android with blootooth pairing to the UNI-T UT383BT lux meter to see how accurate it is compared to the Apogee SQ500 quantum sensor, a highly accurate PAR meter.
I test using the ARAY 2 +RED which has 3500K white leds and added 660nm reds. The setting on the App was set to high CRI LED 3000K and the readings were 92% accurate.
I will be working with the App developers to see if we can improve the accuracy with updated calibration for the most common LED grow light spectrum on the market.

When growing auto flowers at 18 hours light, what light intensity par or ppfd and DLI should I aim for in the flowering phase.and can I dial it in exactly with the growcast controller powered by Telos mesh
I like this collaboration, looking forward to an affordable accurate solution to getting par values for my home operations. Keep up the good work shane you the man!
Shane you're one of the few people that makes internet so precious, thanks for sharing the knowledge and some really useful tips. The only way i can (for now) thank you is by bringing more people to your channel, that i do and will do for a long time ;)
Do people offer to buy you a beer wherever you go Shane? I would. Thanks for helping us the way u do. Yell out if your ever in Aus 🐨 🍺
yeah! cr :)
This PPFD Meter_android app has made my last two grows rather impressive.
If I do say so myself. From a single cola bud on a 14 inch stem to 553 grams
(Wet weight) between two smallish plants (topped autos) all because the cost
effective (cheap) manufacturers light specifications hanging height and Zero
about the dimmer. Stunting growth Too bright. PPFD meters from $350 to $550
this will no do. Using a $40 UT383 BT Lux sensor with a +/- 9% accuracy. I'm
all in for that solution. Working great. Thanks again...Tony Firehelmet
I have this app, Im just using the light sensor on my S9+. Calibrater to the par maps of a mars hydro 1000 and 2 spider farmer 1000s. All 3 are about one year old. It is surprising to me the drop off I have on one of the sf1000s. One is about 65% of what the mars hydro is putting out, the other sf1000 is about 80%. The mars is doing the bulk of the work in the middle of the 2 spiders 🕷.
This has kicked me in the ass to get a new light set up. Thank you Shane.
...been struggling to get my autos to grow to the advertised
height...not even close. Too much light to soon and nutrient poisoning
has been my undoing. Got the UNI-T Bluetooth Lux meter along with the PPFD app
works great. Tossed the old Lux meter in the bin. Thank you for all the
work posting...A.C.Feuerhelm
I'm having exactly that problem on this run :-)
Autos running 24/7 and DLI through the roof!
I've got the squattest plant you ever did see. Leaves laid upon leaves laid upon leaves!
Nice buds though :-)
Check out your VPD as well if you haven't!
Thanks for all your hard work, much appreciated Shane. Keep up the great job 👍
Shane you are a legend!
Thank you so much for your work.
Got a Uni-t 383BT on its way :)
Keep up the awesome work!
I can’t find one anywhere.
@@North39 aliexpress has them
@@North39 ebay there about 17 pound lol
Happy Days. I like this app and noticed this on the update. I think its pretty accurate. But the main use is to use it as an average check so to see where the light is in different areas and not really looking at the numbers. That's what i find most useful.
Agreed, even with 90% accuracy you can plot the PAR levels across the grow canopy and play around with hanging height to remove hot spots and get the most even coverage👍
@@MIGROLIGHT Yep as i found out with my mars ts600 its light is off-centre to the left by about 3 inches or more. And slightly higher in numbers on the left hand side away from the inbuilt PSU. But again very handy to know.
you are the men, my men:))) thank you for your work and honesty:))) wish all the best to you:))
Been using the Uni T since your last. Ppfd vids..found it to be a great help Thanks for the new info
Same here, I got one asap!
Where did you buy yours? Only seeing them from China and would prefer to not wait 5 weeks lol

Using the Uni-t meter under a Mars Hydro TS-1000. Calculating par by multiplying the lux by 0.017, if that's correct. Seems to be working really well
Migro should be in the next Avengers movie for sure. True hero 👏
That's great, not everyone can afford a 500$ par meter I'm waiting to see how you make out, before I purchase a lux meter on Amazon for the second time ,the first stopped working in 3 months,
that's awesome news about the android app collab shane. well done, can't wait.
Thank you for great review and effort for people who cannot buy high end products. It will be great collab too thank you.
Man, your channel is pure gold
Cool, finally an affordable accurate app and meter. Please include geeklight in the calibrations 🙏
Outstanding dude, much respect and appreciation for all you do
Shane, you are building your Legend!
Thanks
Great work Shane - Have this lux meter and works great - looking forward to seeing how accurate you can help get the app to run 👍🍻
That 8% difference might be attributed to the temperature value that you used. Maybe the meter is actually more accurate than that. Knowing the Kelvin temp of the light is a little difficult. I guess you could get a meter for that. But, like previously stated, the accuracy of the PAR is not really what is important. More so, getting an even spread of light over the entire canopy.
How do I know which led setting to choose from on the PPFD Meter? There are so many, lol I'm running a Phlizon 3000 full spectrum linear led. Any help would be great.
Thanks Shane for you Hard work 🤟
I can't get this thing to connect to Bluetooth. If I hold the power button like other people have done, the device just switches itself off 🤷🏻♂️
So if I have a qb with white, red, ir diodes I should be selecting high cri 3k? I've been going white+red+blue
Wondering this too
Thanks much Shane ,,, I have the uni-t lux meter with blue tooth and this add app should be nice ,,, I've used the uni-t app ,,, really enjoy your videos
Happy growing!
Been testing this... it works very well..
Excited to watch that 1 ! Been using that app, hey its not ment to have that bluetooth device but just using the camera!
This is going to change my game no more guessing buying one tomorrow 🤩 Shane your a diamond
Great person this guy is 👏👍😎👌
‘PPFD Meter’ app no longer available for iPhone, are there any new apps?
I downloaded it on my phone and it says the sun is like 1,480 ppfd so I think it's pretty accurate. I have it set on high cri 3k leds
The sun is over 2,000
@migro any chance to get an update on that colab with those fine folks from the app? Just received my uni-t, and I'd love to hear about how things are going. Thank you!
Hello, I am the developer of the PPFD Meter. Things are going great! We have just released our PAR Map feature. If you haven't got it yet you should in a couple of days and thanks to Shane for early feedback while developing!
@@candaspamukcu6872 nice to hear from you! I'm actually a QA specialisrt in the software industry, if you need help or input, let me know! I'd be glad to help. I have about 10 mobile devices for work (both ios and android on a wide OS spectrum)
This is a brilliant experiment for people who can't afford par meters.
Happy growing!
Great content! I bought the UT383 after your last video about it, now I need to get the BT version 😬
Ah, that sucks. Ive ordered the bt, should get it soon.
No you don't, whatever the reading in Lux is on the uni-t multiply that by 0.017, so if the Lux meter reads 15,000 Lux multiply 15,000 by 0.017 which equals 255 par that's alot easier and quicker than mucking around with apps, phones and Bluetooth
@@tucker2074 it is true?
Hey, did you ordered the bt version?
I want to buy the classic version but just wonder if they are same in accuracy
Hallo, ich habe nichts verstanden wie man es jetzt zusammen rechnet mit der App+Luxmeter ???
Hi Shane, love your videos super informative. Getting my first light vipar spectra p2000 2023 upgraded has 3000k and 5000k what stting would I use?
The spread sheet in the description would be nice
Love you buddy!!! Save my day!!😘😘😘
On the spec sheet for my grow light I'm reading the following:
continuous spectrum of 400nm - 780nm and a "Human Eye Appearance" of 2300k and 91 CRI.
What should my selection of source type be on the app?
Hello, what do I have to set for source in the app if I have the Sanlight Q6W Gen2? Thanks for the tool
Legend !
My ut383 by is paired to my phone but it will not connect to my phone in the app. What am I doing wrong??????
Is there a source for these that isn't shipping out of China? I'm impatient and have had to wait months for items to get through customs before.

...it's in a shipping container somewhere in the China Sea...eight weeks to get mine. Worth the wait compared to Professor Bugbee's (from TH-cam) 500 dollar Quantum meter.
@@tonyfeuerhelm only took about 4 weeks for me to get mine I think. Definitely worth the wait.
Just downloaded the app, ordered the uni - t . How is the collab with the producers of the app so far Shane ? Thanks for being out there to help noobs like myself into the overwhelming world of LED Light.
Dear Shane, what is the best spectrum to choosein the ppfd app for marshydro ts1000, tsw2000 and sp3000?
Thanks in front
Wondering if you can help me. When calibrating the ppfd meter app, what should I put in? Spiderfarmer se3000 FULL SPECTRUM & DIMMABLE: Full spectrum (380-410nm, 660-665nm, 730nm,3200-4200K,4800-5000K. Any info would be appreciated. Thanks for making great videos!
I have the same question but it looks as if the guy that posted the video isn't answering this question for some reason.
@@elizabeth-2213ahhhhh welll sounds like u kneed 2 kall the WAHHHMBULANCE🗣💬🗯😮😮😂🤣😂👌
I'm using the beelux-01. I have no idea what setting to use it on been using it on blue ÷ red... I have blue red and white lights do I used the settinf for blue red and white? Pleads help plants in trouble
Very interesting. Thank you!
Top work is there gonna be an iPhone app available soon?
How accurate are the PPDF Meter- grow light meter you down load on a android phone. I just downloaded an app. Specs of my light say 1350 at 8 inch away. The meter I download said the same
That’s great to know but I got an iPhone. What’s ppfd meter app works for iPhone?
Would love to see a follow up video on how accurate the UNI-T with Bluetooth side by side with a more accurate device as Apogee or SpotOn sensor.
I am using the PPFD meter app with the UNI-T but it seems quite unreliable.
But you could make a video comparing the SpontOn or Apogee along the UNI-T and the app i will give a pretty good understanding if its accurate and if not if it show more or less PPFD than the more accurate sensor.
Thanks for your awesome work!
I agree, this UniT thing is garbage. I bought one & regret it.
hi! huge fan. videos are always do informative. Is the PPFD Meter app on Android more accurate now in 2022?
Can i connect that device to my iphone with photone app
so is this a legit way to test light intensity that everyone can finally afford? I was gonna pick one of these up on amazon theyre like $30 but they only have 1 review.
Hi my friend. Im trying to download the app but tell me that may phone is not compatible with the app. My phone is a xiaomi mi4c. Another thing. I have a par meter LightScout 3415FSE) from few years ago, and looking the datasheet i dont understand the spectral response. In the 400nm say 0,1 photo sensitivity (a/w). In the 500nm say 0,2 photo sensitivity (a/w). In the 600nm say 0,3 photo sensitivity (a/w). In the 660nm say 0,2 photo sensitivity (a/w). Thats a good spectral response or very poor??? Thats enough spectral response to read good the ppfd from samsung lm301h 3000k ????? Thanks a lot my friend.
The PPFD meter app is giving me an average Lux of 4000 lm/m2 per s on my pretty cheap grow lights. When I look online it appears the typical PPFD par reading is in the range of 250 to 500. But it appears that reading is done in micromoles/m2 per sec. This is confusing and I don't see any explanation in the app notes. Can anyone explain how to interpret this reading?
Hey mate seems like you are mixing lux and ppfd. Lux Meter shows what your sensor is reporting. App, just displays what it gets. You should use PPFD & DLI. All the displays have their respective formulas. Happy growing.
When you pair this up do you still have to calibrate it to a intensity level you're expecting? Or should I trust the uncalibrated level of the uni-t paired with the app?
Hi,
It still needs to be calibrated to the spectrum your fixture produces.
Thanks.
you are greattttttttttttttttttttt
Any updates on the app? Is it more accurate with the BT UNI-T then to just take the LUX value x 0.017?
Thanks for all your work Shane!
Indeed our conversions are much more complex than (LUX value x 0.017) you really should try it.
@@candaspamukcu6872 Would love to see a follow up video on how accurate the UNI-T with Bluetooth side by side with a more accurate device as Apogee or SpotOn sensors.
@@arn0ld2000 hahah then you should watch this video!
Been sitting here trying to pair this dang thing for an hour.
@MIGRO hello sir, there was a website i remember seeing before from you pretty sure where they take in requests for lights and they test every aspect and listed the numbers on their website. Do you remember the link to that? Thank you sir!
doesnt work for my phone, Do different phones have different sensors?
Stoner thought... Is the measurement height above the canopy/table top? Or is it measured above the meter height? If that inch or so of meter height isn't accounted for, wouldn't that change the results?
Hi, I measure from the top of the sensor to the underside of the LEDs
whether the calibration should be set to -9% Low CRI 3500K
Are you not supposed to put paper across the camera?
What comversion rate would be used for a light that is advertised as a full spectrum, specifically the tsw2000 from marshydro?
You can select 3500k setting for MarsHydro it uses 3000k + 5000k whites -> average is 4000k and since it has 660nm on top selection should be 3500k
@@candaspamukcu6872 thank you 👍🏻
@@candaspamukcu6872 are you guys going to make a PPFD meter app for iPhone? Right now I’m using the UNI-T and converting to PPFD using an online calculator. Your app looks nice though
I would like to buy this light meter, but the link is to the manufacture and does not allow orders. Where can I buy the _right_ meter. Amazon or eBay show a wide variety of the meter, just want the same model you tested and not a knockoff.
I bought the light meter on ebay.
##Tip: Buy from someone in your country with stock. Expect long shipping delays if you buy from China! ##
I love it! It works exactly as you described. I've used it to create a light map of my tent and to determine my correct hanging height.

There is an IOS app in development.
Yes you would need to do the multiplication, check out the video below.

@@MrE1981 I have a conversion table clipped to my grow tent with 100 lux increments 1800 LUX (306 PAR) - 8100 LUX (1377 PAR) best thing ever. THANKS SHANE. Still complicating my life with an app sounds like trill AF!
@@MrE1981 Shanes other videos are why I got the Uni-T and I use the conversion rates he has kindly worked out and shared. Agreed its definitely not needed when you have the other version but like a magpie I like to collect shiny things ✌
Me too
How accurate do you think it might be with just a standard 4000k light with no far reds added like a Samsung F Series gen 3 or H inFlux strips?
About 90% on the correct setting. We will work on increasing that accuracy over the next few weeks
Who or where did you get the UT383BT from ?
Aliexpress.
average price should be around 20-25$ including shipping on Aliexpress
Добрый день Шейн. Спасибо за обзор, это очень полезный и нужный прибор для домашних агрономов. Не сомневаюсь, что вы как человек любознательный провели проверку прибора под светом ламп HPS 2000к и HPI-T 6000к. Скажите, если это не секрет, на сколько люксметр точен под этим светом?
Would try again in english lol

Hello, I am the developer of the PPFD Meter. We are planning to work on better source options this year.
@@candaspamukcu6872 I'm using it with this device now. Much more accurate than the photon app with android. My readings now are very close to par maps provided as well as par readings done by migro at similar distance with apogee quantum sensor. Keep us updated with any changes

indeed true. That way you don't need to put -8% calibration.
Hi.
If my quantum board has 3000k, 6000k and red, would this equate to 3500k. Im sorry for the stupid question. Great vid as always.
Good question, I would say use 4000K High CRI for most accurate reading

This channel is pretty useless now since Migro will answer you unless you ask him about a iphone app for this device. Then he ghosts you. He also doesn't reply to questions about calibration. I bought the unit & it is complete garbage. The numbers fluctuate & it is usually inaccurate compared to a true Lux meter. This is a gimmick. IF YOU HAVE A IPHONE....DON'T BUY THIS.
