ESP32-C3 based Smart Door/Window sensor | DEEP SLEEP 30nA? | Long battery life 5/10 years

Impressive result
If I understand correctly, the RC delay (R10, C8, C12) is basically the time for MCU to respond and latch on the main MOSFET to prevent the circuit from switching off again?
Toggling AUTO_TURN_OFF must be the first operation after the MCU wakes up?

Thanks for sharing. It's very inspiring. ❤

Excellent piece of work.

Salvator, Can you pls post link to buy Frogo pins programmer?

I tried makermeik project and the logic circuit to enable ldo does not work as desired. On one pcb it worked i dont know how but on all others it failed

Very nice project, i like it. I see is not so easy to reflash once the module is assembled. Have you thought using the over the air reflashing? Well to implement that may help you, but it will also depend how often you think you need reflashing the modules

Would it be possible to do this with an accelerometer interrupt instead of reed sensor?

Very nice, thanks for sharing. I was struggling with the same idea on remembering the previous state. Interested to see your github

Very nice done. I like it that you grab yourself the target and keep on improving it. It’s a nice combination of mechanical and electric engineering, like the details on the battery bay and the lid. Details.

Although I also very much like the versatile and addictive ESP-32, could you imagine using a more power friendly chip?

👏👏👏👏👏

Bravo, anche per il video editing.
l'inglese é un po' da migliorare.

You are a creative man..always waiting for videos of your beautiful projects...how much will you set a suitable price for them??

I will try to implement this. looks good

Very nicely designed. Helpful for smart homes. Cheers

how sexy are those 0.8mm boards! I love them in my projects.

Man, how much simpler would home automation be if you could just project an rf field around a house and tap that for energy? I'm working on weight sensors for my gas storage to detect leaks and warn me when one of the two bottles gets low... it's got a pair of 16550's and a solar panel...

Very well thought out project! Nice one

Well done, man!

That so cool 👍 Can we have a video from you explaining how to design pcb for low power device because you are so good at it

So Genius 🎉

Amazing project

Good engineering, well done. I like all the simulations and research you did before diving into the PCB design. That circuit is complex though, are you trying to simplify it or are you ok with it?
