Excellent Professional Video, content was sufficient, informative, and detailed. The actual data results speak for themselves. Now how about grabbing the data remotely via WiFi 2.4ghz on just the tracker and piping it back real time (every 3-5 minutes) to your Home router so You can monitor and track it on a Raspberry Pi attached to your home network? Great job, you will go far at this pace!

It's fantastic

How About Using a Coco Peat, Instead of Clay Balls. Therefore Having to Irrigate only at Certain Intervals? Do you think it would Work? And have you Experimented with Other Medium?

What is the adapter that you used?

Is there any idea how to pump the water fish tank up to the grow bed through bell safon without water pump?

Good stuff!

Thanks Jessica ❤ I subscribed you. Thank your for this video. Great video quality, great audio quality, great and clear speaking voice, great explaination ❤ most of these Arduino videos are made with poor poor quality, with poor English, with poor audio and video quality, with background-noise... your videos is shinning like a star... I really really really really have to thank you. You made my day ❤❤❤

This is absolutely electric work! Congrats on 1k subs. I was 999 and my alt account, Sadie Enward, was the thousandth. Because I was your 1,000th subscriber I would like you to send me a plant. My address is 4413 Shepherds Lane. I like Venus Fly Traps if you have any. - Boo Bees

Mam, will you let me know what is difference between pH meter V2 and pH meter

Hello Jessica, i sent you a mail and waiting for your reply

The issue fixing was great, thank you😊

Do a vertical biracial experiment

Smart!

Great Job... Would have like to see a comparison of 1 Axis and 2 Axis solar tracking efficiencies...

hey thanks have you tried this with a poly crystalline panel?

Great video Jessica. One comment from me to help others. When first trying the sensor, put it in PH 4 solution. If you tried before calibrating with tap water you will get PH error. Use right fromm the beginning Solution 4, calibrate, use solution 7, calibrate and done!

That's beautiful 👌

Great presentation! Thank you. When there is not room for more panels this is the way to go. Solar farms in the Northern US are using single-axis trackers.

Great video. Nicely done. I do wonder if there would be a way to hook it a computer and record trends over time and compare that to weather conditions from a home weather station, use a photo resistor to record the suns intensity etc.

Fixed systems should not be 'flat', they are at 45 degrees facing south for optimal sun exposure. You should be tracking energy spent on servo vs overall power efficiency of stationary vs tracking system. Results may surprise you.

It was a good video. and since you do hydroponics vs soil based gardening it meets your needs. I wish they produced a soil PH sensor

Can you please tell me specifications of your solar panel? How many volt & watt?

great experiment and data collection. did you account for the power used by the motors to move the panel and how did that effect the benefits of tracking? can it scale up to a 200w panel.

My understanding is that a tracking system is not necessary or cost effective in every application. For ground mounted solar arrays it's cheaper to just add additional fixed panels to make up for the lost watts. With fixed panels there are no moving parts to maintain, repair or replace and the system as a whole is gobs cheaper, even with additional panels. For backyards with limited space and only a few large panels/arrays on poles a dual axis system makes sense. If you look at most big solar farms they are fixed arrays/no tracking.

Good video, have you thought about doing a dual axis to see improvement with a dual vs single and fixed?

Very, very well done! A controlled experiment with detailed scientific analysis of the collected real world data. A pleasure to watch & learn!

while rerunning the program, after modifying begin function, you didn't uncomment the ph.begin() line in main code.

Greate job this is simple design but power full . thank you.

Hi Jessica. I have the Eco Worthy dual axis tracker. I have 2 arrays. All panels are identical; Trina 400w. 1st: 2 panels laying on the ground, tilted about 12" and facing West. 2nd: 1 400w panel on the tracker. It has been averaging just over 1 KWh a day.. 1.8KWh\312w, 1.16\320w, 1.12\317 for the past 3 days. Late yesterday after the sunset, I added a 2nd 400w panel to the tracker. It's now getting 1.24KWh. The 1st array is getting 890Wh and just 417w. So YES.. trackers work.. I have 6 new bi-facial 200w panels arriving on Friday (1200w) which I will mount on the tracker. Overall these 2 arrays make about 2KWh a day.. but that will go up drastically soon. I have a Victron 150\100 for the 2-400s and a Victron 150-45 for the 2nd one. I have a video on my channel of it. You should do this same test with a dual axis tracker. I'm certain the numbers would be more..

Again as others have said, excellent work and excellent documented results. I have a several of comments: 1) You should view another TH-cam experimenter who demonstrated a "genius setup" tractor of two large solar panels balanced via a hinge on a see-saw horse whose panel tracking is automatically done ONLY by an additional small pair of steering solar panels powering a $20 motorized actuator arm. No sophisticated computer serup! It's an extremely simple setup. The key is to reverse the power leads from the small steering panels so to supply voltage in an additive/subtractive method to the actuator arm's stepper motor, by changing voltage director to the DC motor, as the Sun moves across the sky. Thus advancing or reversing the tractor's DC motor direction and the large solar panels position. 2) In your "fixed solar panel" experiment test you placed it totally horizontal, flat eg 0° degrees. Whereas, in actual fixed solar installations installers set the fixed panel say at 32° deg angle to face the region of the sky where the maximum Sun tracks across the sky at higher intensity say 10 AM to 3 PM. Perhaps if you had placed your fixed panel in a similar angle Sun facing way, it seems to me you would capture more solar power for the day. Perhaps enough, where the power differences between fixed vs tracking would be smaller. (Maybe next time.) 3) My thought considering how complex and expensive Sun tracker systems can be to gain a 25% to 30% improvement, wouldn't it be simpler and more cost & power effective for home setups just to add an additional fixed non-tracking solar panel. 4) Again, you produced EXCELLENT data comparison results of a single tracker vs a fixed horizontal panel. You Go Girl!! - Paul

You keep saying that you have a list of materials in your description box. I cannot find this. Can you not show a list during the video?

is it nessary to really open the sensor

Why fixed panel was horizintal? Do You live in/on equator? If not, optimum angle should be used.

To give a little context, the ballpark figure that most people throw around for tracking systems is up to 30% improvement in harvest, so your results are pretty much in the ballpark.

I think the tracking system would have started off earlier then 7:30 AM.

I really like this presentation, and good info. Just subscribed.

Thank you, most clear and straight forward clip! It will be intresting to have a 3d tracking sistem :)

awesome

Very clever, cheers.

I have a Problem i can enter the PH calibration MODE with “ENTERPH” but not able to “CALPH” when I enter this word in CMD Serial monitor nothing happens.

This is great!

Good luck.Thanks for video ;)

kindly share how you connected the rest materials

you are so amazing❤️

Hey, I have done that part and also wanted to generate a report on the comparison between fixed and tracking solar panel, what materials do I need to add and how should they be connected. also how do I add a notification feature to the project?

can this solar modified to lamp with iot ?

Hey jessica....do you have proteus design simulation of this solar tracker? If have can you please sent me via email

Is it possible to combine the pH sensor and temperature sensor in UNO R3?

good job!!

So it means that if increase 24.56% more solar panel than our existing system, we can get output of single axis solar system. I think it is better way than moving system.
