This is way better than my idea of a triggboard controlled thermostat! The cheapest wifi thermostat you can buy on Amazon is nearly $100? Thats crazy 😃
Your approach is great! Thinking about longevity surely we could implement a solution where the fresnel lens knows it deadness regarding previous inputs. UV light kills them over time; I'm forever as an electrician replacing PIR sensor lights. That fresnel lens most use aren't UV stabilized.
In the past you tried working with the nrf24l01+ modules, why did you stop working with those in combination with for example a atmega328p on 1mhz ( which i think would be sufficient). Would that not lower the power consumption even more. Inunderstand that it is more complex for configuration purposes but just on the power consumption part, would that be more efficient? ( also using an rtc for sleep / wakeup interval just like on the trigboard ). The voltage on 1mhz is also has a wider operating rangr. Really interested in your thoughts.
can dramatically be improved it by using LoRa instead of hungry WiFi imo but thanks for this nice video, i like it :) What do you use to measure ur current ?
Hi Kevin. Another great vidéo. I remembered a vidéo you did with that cheap pir detector. You were using ferrite to avoid false triggers ... You did not need them anymore in this new setup?
How about just powering up the cheap sensor once a second or so to reduce power consumption? Would they work if they are on for a fraction of a second?
My am312 is now showing 3ma in standby, a few months ago, it was ua when I first got it from what I recall.... I may have put some current into it by accident when I was reprogramming my MC which may have cooked something, but thought it has a diode on the am312 module.
actually both shown here, but I have not seen much of a speed change. That AM312 demo spends most of its time waiting on a response from the pushover server. The Panasonic demo doesn't need to do this - instead it connects to another ESP32 acting as an AP and hands a packet over via UDP and goes back to sleep immediately. It does connect with static IP though, but again I don't think it really matters. Maybe with some routers this is slow though, which is why I provide both options in the configurator
@@Kevindarrah It would be neat to see the power draw when using dhcp. Static IP assignment just does not scale. Have you ever looked at LoraWAN sensors I think you would really like it they are designed to be very low power.
Everytime I get stuck with something, you appear right on time with the answer I've been looking for all over the whole internet. It's crazy!!
cool!

great stuff! would love to see more people competing for low power devices like this!
Great update 😊
Interesting as always 👍🙂
Thanks for sharing 👍😊
So Awesome!
I never heard of it either... and that trig board too. Thanks!

I subscribed, just because you use less or no libraries!

I am no statistician, but a 2uA version over a 1uA version makes a HUGE difference in the grand scheme of things.😅

Sorry for those crap french accents!!!
For info, I tried those pir sensor with my.trigboard clone but even with ferrites I had a lot of false triggers...so I gave up
actually on trigBoard v8, the power supply topology is better, so I think that' why I haven't had any issues with these PIR sensors.

Hi kevinn,
what brand/make current Prob/DSO you used to measure and analyze the current?
Otii Arc
Great job can you do for smoke dectector
yea, been researching that one for a while - that's on the list!
When you say connecting to a WiFi network, does that include getting dhcp or static?

Is this board open source?
First ;)
