Flammable gas & CO detector - test and teardown
ฝัง
- เผยแพร่เมื่อ 27 ธ.ค. 2019
- Today, let's take a look at SAFE-808 COM, a 2 in 1 combined detector of combustible gasses (like methane, propane, butane, natural gas, CNG, LPG, ...) and toxic carbon monoxide (CO). It has an alarm to warn you in case of a gas leak or CO leak. It can help to prevent an explosion or gas poisoning (suffocation). Let's "properly" test this detector and also see what's inside and how does it work.

17:27 "Some 3-pin chip, an 8-pin chip, a-lot-of-pin chip..." You got me.
Ah yes, I'm well familiar with the SOP-a-lot-of-pin IC package. Very common.
i know im asking randomly but does anyone know of a way to get back into an instagram account?
I was dumb forgot the login password. I love any tips you can give me!
@Otto Duke instablaster =)
@Julian Brayan thanks for your reply. I got to the site on google and im trying it out now.
Seems to take quite some time so I will get back to you later with my results.
@Julian Brayan It did the trick and I finally got access to my account again. Im so happy!
Thanks so much you saved my ass !
2017: even more salt
2019: even more carbon monoxide
sweet death
This guy's accent makes his videos like 1000000x better. (No offense)
His accent is the best
What accent is it
@@barrybritcher Czech
Yes it does.😏
@@westelaudio943 I am pretty sure he mentioned something about Slovakia in one of his older videos.
Fun fact. "Pozor" in Czech means "attention" while in Russian it means "shame"
Fun fact: "Tae" is a common name in Korea, while in Philippines, it means "Poop". However, the pronunciations are different. In Korea, it's pronounced "tey", while in the Philippines, it's pronounced "ta(h)-eh".
in Polish we have a similar word "pozór" meaning semblance, guise. In the same manner, "plyn" in Czech means gas, but in Polish "płyn" means liquid. Languages from the same family tend to have a large number of so-called "false friends".
Artur Twardowski yea, the same situation with polish "sklep" (shop), in russian it means crypt or tomb
@@FatalBombCRV And "chyba" means "maybe", not error. And test means test
@@Kyleroo Looks like, it's funny-word time...
In german, the word „dick” means „fat” or „thick”, but in english...means something different:)
You have the best Christmas tree I've seen in this season.
15:27
I respected your hesitation to open but after some seconds you got me by telling "its a joke"
It's weird seeing something relatively well made that works as expected in the channel.
11:40 Put one of these in a garage with an old 80's American car with a carb. The LCD display will literally go to >999 and the unit goes ballistic when you start it up.
And a lot of chips.
3-Pin Chip, 8-Pin Chip, A-Lot-Of-Pin Chip. :D
You got me there again..
This device that you just teardown is one of my favourites so far, keep up the good work man, this is amazing!
The carbon monoxide experiment is AWESOME! Thank you Diode! Happy new year!!
thank you for education on this and CO and flammable gases I have or may not smelled a natural gas leak in my life much but I appreciate it DiodeGoneWild
That stove is too clean! You spend to much time in the lab 😁
Happy New Year!! With many achievements!
Thanks for the gifts under the tree, Danik. very appreciated!
Happy new year to you and all of your family relatives.
P.s. the heated sensor probably had limited life (about 5 year)
Due to heating, the reaction with the gases went poor and bad so the sensor becomes insensitive.
CO sensors have a limited life (my CO-only alarm in my house has a "replace by" date). They're electrochemical, and after a period of time the chemicals run out.
Merry Christmas for you too! 🎄
You have great sense of humour, with the Xmas tree and presents as well. Thanks for explaining the gas rings. I noticed sometimes the flame goes out after initial ignition - I never understood why I had to hold the igniter a bit longer. Now I see it's not really the igniter, it's that heat sensitive safety valve. I like the interesting things you show us, I enjoyed the green flip clock very much. Regards from New Zealand.
15:28 You nearly got me :D
*Proceeds to void the warranty*
I'm from Poland, but i'm very like Czech people!
Merry Christmas and Happy New Year. I'm really looking forward to seeing your new Tesla coil.
Feliz navidad!! You are the bigest!
In Romania it is mandatory to have it as safety device. It is connected to an electrovalve outside the building and that electrovalve stops the gas. You must reset manualy the electrovalve after an alarm.
It might be worth stressing that CO is produced by incomplete combustion of *any* fuel - wood, coke, charcoal, paraffin (kerosene), coal… Not just gas. The candles experiment highlighted this. It's worth installing a CO detector wherever a heater is installed unless it's an electric heater - it's a legal requirement to do so in some places.
I had no idea what those safety things from the stove do, up until now. And I also realized my stove has holes for them, but it doesn't have them! Moreover, I should get myself a CO detector, now that you mention it.
All the best for 2020!
Wow. That CO-Sensor is small. Some Weeks ago my CO-alarm ran out of batteries (it was a disposable one with two lithium cells with a lifetime of five years); I took it apart and the CO-sensor-cell was almost as big as a 18650 cell.
Danyku, tvoje anglictina mne na tech videich bavi uplne nejvic :) Palec nahoru
Thank you! Very interesting!
They are probably telling you to use specific batteries because it's a high power load. Some 9V rechargeable batteries are really crappy and go very high resistance after a short time.
Nice review
Diode gone boom basically
MC34063A - buck/boost/inverter switching controller
YX3P087 looks like it might be a audio chip with built in voice samples
other are dual opamp, ac to dc controller and 7330-1 is linear voltage regulator
Very artistic tree!!!! Merry Christmas and Happy New Year
Ogólnie dobre filmy,
Oglądam od dawna
Pozdrawiam ;)
Haha thats Funny tricking us about the safety sticker......Merry Christmas Mate from New Zealand.....
Simply thank you!
Merry Christmas and happy new year!!! ^^
This guy's Accent + CAT makes his videos like 1000000x better
Great video as always ! Could you make a video to show some tips about reverse engineering ? It´s amazing how you draw a schematic from circuits.
Awesome videos 👍
If you have natural gas connection, you should install a gas detector that can also shutoff your gas supply upon alarm. Install it near the ceiling.
Install the detector you showed us at ~1.5m from the floor for CO detection. (CO is about as dense as air, so the detector needs to be located at your breathing level.)
I had to immediately rush out and try this with our CO detector. I couldn't get the reading high enough with a candle but a peice of smouldering rag worked fine and triggered it easily.
where is "and heeere's my caaaattt" ?
Even mooore saaaaalt... i mean caaarbon monoxide!
Water spilling everywhere the room is vibraaating!!!
Breaker still doesnt trip!
*EVEN MORE SAAAALT!!!*
Happy new year :)
Ahoj, preco to ma udavanu zivotnost 5 rokov? Jeto zivotnost samotnych senzorov?
Good choice on the TESLA branded capacitors! Very appropriate for the purpose.
can you use the co meter to tune carburetor?
how do you make that watt meter?
Nice. How long did you clean the gas stove before the video? ;-)
Merry Christmas Happy New Year
Good detector thanks
Past: Even more salt !!!!!!
Now: Even more Carbon monoxide !!
The single-insulated wires (what voltage are they rated for?) to the display, running over the top of the primary capacitor, may be a loophole in the isolation; the individual mains wires also get close to the battery positive terminal. Some sleeving in those positions would have been prudent.
Pretty much most of the times you'll need this are when your heat exchanger rots out and flue gasses start coming into your house. Still not as good as a professional one since it tripped when I had a CO issue, but not the consumer unit plugged in near the return vent.
I love your videos!!!!!!!!!!!!!!!
Dangerous dose of CO according to the CDC: It has been stated that a 1-hour exposure to 1,000 to 1,200 ppm would cause unpleasant but no dangerous symptoms, but that 1,500 to 2,000 ppm might be a dangerous concentration after 1 hour.
When did you decide to change your accent to get more viewers DiodeGW?
It has worked rather well!
You now sound like a Scottish Northern lslander from the Isle of Lewis lol
Great video as usual more interesting than Big Clive now!
Dobry Populodnie moja Czechky Kameraden!
Vesele Vianocne stasne novy rok!
I wonder if you could use it to detect combustion gasses in your vehicle's coolant system to determine if the head gasket is compromised.
I think you have to look for CO2 then, not CO.
Dobré video
ha ha ha ha, your desciption is mindblowing
I only read "Flammable" and "DiodeGoneWild". Without further reading and thinking I clicked on the Video and expected something to be blown up.... With that expectation in mind, the first 10 Minutes where a bit boring :)
Nevertheless, again a brilliant Video. I wonder where I got the expectation from, that "Flammable", "DiodeGoneWild" would always end up in a smoky mess ;).
Brilliant
Excellent video, text, English accent. If only I had you as an electronic ps teacher 30 years ago...
But where is the cat?
Great! The natural gas flame detector at your kitchen oven has one more functionality. The are 2 materials /metals connected together. If the sensor is hot, it produces a current which holds open the gas valve. The unknown (forgotten) functionality is : if, for example water is out and the Thing over the flame becomes more and more hot, the other side of the sensor, where it is screwed with the oven, becomes hot, too. So the temperature difference delta becomes lower. Because the current exists because a temperature difference, the current becomes low with less delta of temp. difference. So overheating the sensors bottom will a clo the gas valve. I hope, it is understandable, what I want to say 🙄 After terrorism against me at Infineon Regensburg and 2 brain bleeding my English has become bad.
A good product.
I have a ch4 detector at home too , when it detects gas it beeps and then shuts off the valve at the gas meter to stop the gas from entering
One of the holes, where it can be hanged, is directly behind the high voltage part.
You're right, but those holes are not meant to hang it. The plastic base has to be mounted or hanged onto a wall and then the detector slides onto the plastic base.
Když Čech mluví Anglicky. Super video.
Prosím, chci se zeptat na jaké prvky se ještě váže uhlík, jestliže existuje pouze CO², jestliže Jeden uhlík je čtyřvazný a kyslík dvouvazny, tudíž u značky CO zbývají uhlíku dvě packy volne a podle fyziky by ani jedna neměla číhat.
Já teda nejsem nějakej velkej odborník na chemii, ale molekula oxidu uhelnatého (CO) obsahuje jen jeden atom uhlíku a jeden atom kyslíku. Co se týče vazeb mezi nima, něco je na wikipedii:
en.wikipedia.org/wiki/Carbon_monoxide
You have Gorenje cooker.Right ?
i've recently heared that if natural gas has an orange-like colored flame, it means there's not enough oxygen and i assume you can get CO in the kitchen that way?
Not bad!
Why are the LED's "stupid"?
Nice, A Lot of pin chips HERE and THERE!
That's the best Christmas Tree, No Led's Here! |:-D
Happy Holidays Everyone
Nice
Jor ingliš iz prity gut tvl fakt nechcem vedieť jak znie keď ''mluví" lebo jak on to ťahá (karbon dioksaaaajd)
That's nice! I hope it was a Christmas gift! 😂
Žárovky jsou nejlepší!
The flammable gas sensor needs to be heated like an automotive O2 sensor to work so it gets hot, though its based on a different technology.

Test some chinase tester like this, but with fully functional double detection as this
Man ! that lady inside the gizmo screaming at you is brutal !
Better leave that 2 pin speaker connector unplugged to ensure good night sleep....
hey man, can you write me the limit of these gas in ppm?
13:30 You will be death and allarm will be silent. Nice.
15:26 We are all waiting for this. 🤩
Gas detector is 2 pin and CO detector is usually heated - 6 pin. You need made some magic with resistors for better sensitivity of CO detector.
I'm waoting for next video.
Ty jsi z Čech?
I think someome should do smart Windows, wich open, when there are poisounos gases inside.
*Burgler pumps some gas inside.
*and ur fucked cuz all ur stuff is gone*
@@revolution5547 install it somewhere burglars cannot reach or add a grate in front of the window
Kinda dumb. If you have co, you have a fire near. If you open the window, it'll get bigger
@@mernok2001
that is the best idea , it will stop poisonous gas and explosive gas whichever set it off :-)
maybe the big cip whith no marking has the voice recordings on it
Wait, what? You have plug in CO detectors in Czechia? In NYS they have to be permanently connected to house wiring and backup battery or have a preinstalled non-removable battery which can power the detector for 10 years.
America has plug in detectors too. First alert and kidde make them.
I want one of these with the voice in czech or another language
Dangeroooos
moc to žere když je tak drahá elektřina :)
Pretty sure that voice said "Protect cat, all other lives expendable" ... ur cat has mad program skillz
Hahaha :D
"no stupid led's"
yeah I hate them too..
I wonder, if the voice actors for those things always record their samples at 3 in the morning, after party or on crack etc... Especially the czech ones, I never heard any that sounds normal.
Right, we can sound pretty funny sometimes😁
9:55 AHAHAHAHAHAHA
You not take something interesting apart .. ha ha :-D
All that device needs is a massive boost of sensitivity so it detects farts, and the noise of a fart comes from the speaker :-D
Sorry i have a silly imagination :)
Methane gas LOL
Hydrogen sulfide detection :)
Wtf
10:44 blyt cycaa 😂😂
I think you should have a paypal link as well, for all the people who would like to make a spontanous donation. highly recommended to have as well!
When natural gas (ch4) reacts with oxigen (O2), aka burns, the result is heat + carbon monoxide + water vapor. Ch4+O2 = heat + CO + H2O
But this reaction is metastable, it mostly create CO2, because the bond has lower energy and that's what nature wants, the CO bond is double, so ii needs more energy to create and to keep.
I had this in the past in the kitchen over the gas stove, but it detects hair spray used in hall by my wife. We have kitchen next to the hall without door. So I had to stop using it (detector, not hair spray 🙂).
