Adding IoT to a Smoke/CO Detector with ESP32! (trigBoard) with 3 wires!

[@BloodAsp]

We need more people like you that value ultra low power consumption.

[@user-qf6yt3id3w]

It's weird actually. Hardware designers who know about ultra-low power are rare as are software designers who care about getting the best performance out of cheap/low power hardware. Instead, engineering degrees teach people a bunch of stuff that results in designs that result in the exact opposite of both.

I love the shade thrown at 140 microamps standby.

[@Kevindarrah]

had to!

[@Nimbos0]

If you ever thought of doing more videos like this, I would be more than willing to watch them :)

[@marvinfuller8069]

Excellent demonstration of the versatility of the Trigboard (and configurator sw). Well done, my friend!

[@chiparooo]

Very cool. Nice extension of the trigBoard. Thanks for sharing!

[@FrankGraffagnino]

would love to see more trigboard recipes like this that involve modifying existing equipment to make them "smart" with total local control. Another one that would be cool would be a commercial motion detector that is easily modified. But could be others, like automatic watering things for pets or plants, all kinds of stuff

[@Kevindarrah]

thanks - yea good ideas!

[@beatlessteve1010]

Once again a man after my own arduino heart...i would like to see a diy xrf analyzer!

[@chlordk]

The Figaro TGS 5042 CO (Carbon Monooxide) sensor uses much less ampere than the other I have seen. Very interesting.

Looks good though when I looked on Amazon that smoke alarm is quite expensive almost $50 though if it prevented a fire it would be worth it. I have been looking for something like this for my 3d printer. It should be possible to activate a relay to shut off power with this system though I am not familiar with the trig board, but I have used other ESP32 boards.

[@AxelWerner]

Make the trigboard cheaper. 30$ is WAY to expensive. You should aim for

[@BloodAsp]

I think that is because he hand assembles them. Should have them wave/ pick and place assembled for cost.

[@AxelWerner]

@@BloodAsp you think wrong. have you seen the details of the assembled board ?! SMD transistors the size of a sand grain. nobody assembles stuff this tiny by hand. its because he made them 100% locally in America in low batches. to make it fly it must be made somewhere else in higher volume.

[@Nono-hk3is]

Im sure Kevin would welcome investors who will help him cover the risk of putting a bunch of money into a large batch run.

[@Kevindarrah]

yea made here USA 1300pcs at a time - but I did build the first 5 protos by hand!

[@jabhomemonitoring]

Excellent video!!

[@Nono-hk3is]

I know you discuss this in your trigboard development videos, but would you consider doing a dedicated video on how you measure such low currents?

[@Kevindarrah]

yea everybody asks about the tools - just an Otii Arc expensive, but very powerful

[@MobileDoctorMIJANUR]

Good idea 👍

[@BoB4jjjjs]

Was there enough co to trip the alarm? If it detected CO it should sound and keep sounding? Bit strange it just bleeps, if you are in bed and the Boiler/Furness starts putting out CO you would want it to keep going. That makes me think it was just on the verge of triggering. The last thing you need is false triggering. So maybe the CO was just on the limit. Just a thought.

[@Nono-hk3is]

Great idea and execution! I'll reiterate Kevin's warning up front. Don't do this on your only detector. Buy a second "burner" detector to do this.

[@tino2828]

What is the piece of equipment you use in capturing the current drawn? It is shown at 5:53 in the video.

[@Kevindarrah]

otii arc

[@ebb2421]

yep, what the heck is chirping...thanks for the effort.

[@ChrisS-oo6fl]

Can you do a few examples of your trig-board projects being implemented into Home assistant with MQTT or possibly how to utilize the low power capabilities while using Esphome? I know these are primitive questions but I’m sure I’m not the only laymen who’s landed here while just learning home automation and iot in general.

[@Kevindarrah]

yea it's on the back burner - in the mean time I do have MQTT support, so should be pretty easy to figure out

[@thebeginnerelectronicattac8320]

Saw this from eevBlog’s mailbag

[@camrouxbg]

This is nice. May I suggest, though, that you put the board on the table, zoom and focus, and use a pen or other stick to point. The constant handling of the board to show what is on it is really annoying as we can't really see what you are talking about very easily.

[@mickleuk]

I’d love one of these, but by the time you add shipping to the uk it’s way too expensive. Do like Kevin’s videos and projects though.

[@Kevindarrah]

thanks!

[@southwestelectronics4902]

So why doesn't every detector have this ??

[@theevilvegetablepatch9873]

🤣😂🤣😂🤣
