Hi, i am a software developer who has installed a nice LoRa setup inside home, but...
Now it's time for the garden!
I already have a plant monitoring setup using AtMega328P with it's solar panel, it's CN3065 circuit and it's 3,7v battery, all ok?
Some nights the battery empties, and starts charging when sun raises, but the voltage to the microcontroller rises slowly, so it halts due BOD 'brownout' protection. So, i have to go out and push reset button
Does anybody know any easy solution ?
Maybe a diy circuit for makers?
I would appreciate help.
Thank you very much
