I have some self designed Circuit boards with NRF and Si7021.
I do not use them anymore.
Battery is CR123 used in Visonic alarm.
When I replaced the battery on the IR sensor I continued to use it in these sensors.

Contact me if you are interested so I can tel you more about it.

I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system. So please, can we have a 'how to' step-by-step guide to OTA? Please? S.

It probably has to do with fewer people buying them once summer ends, so companies might lower prices to clear out stock before winter.

@wrendral said in "Remote Irrigation with LoRaWAN: LM27313 Challenges and PCB Design": I will go with a Li-Po Battery type: 304048 3.7V 1200mAh Might work, but maybe the internal protection will trigger with the high current peaks. I'd suggest you plan a 0 Ohm, (2512/THT) resistor as R2 and then replace it with a 100Ohm/1Watt if the protection triggers.

Supposedly PIR doesn't work through glass (e.g. if looking for motion through a window), whereas I presume a microwave sensor might still work.
