Good evening. Not posted here in a good 5 years (moved career...now a full time Java/Spring developer mainly thanks to Arduino!). I have gotten back in to Arduino/electronics as a hobby and was just wanting to simply power a small MCU (ATTiny85 or 84) which just uses a DHT sensor, takes a reading …

Nick Gammon posted an excellent tutorial on just such a remote solar powered Arduino sensor. He used a supercap to avoid the battery charging problem completely. See: https://www.gammon.com.au/forum/?id=12821
