The idea is that we can hang them in trees all over the metro area and keep an eye on when they ripen. This is mostly powered by the Twilio programmable data service and the Ai-Thinker A20 (https://www.aliexpress.com/item/DIYmall-ESP8266-A20-Wifi-GPR...) -- WiFi and 2G cell radio for $14!
We can likely get battery life in the range of several months, so we can put the sensors up at the beginning of the season and then take them down when we harvest.
Do you know roughly how big the images that the camera takes are slash do you happen to have any example images?
I have a few more questions that I can't think of at the moment, but I'd be happy to give you a hand with any battery-related stuff (a specialty of mine) if you'd like! My email's in my profile, feel free to reach out even if you don't have any battery questions yet.
I'll drop you a line!
