James Bowman posts about successfully automating reading the status of a chicken coop. It uses a Raspberry Pi Pico doing perform sensing, with a 915 MHz Lora module to transmit the status back to the base. It’s powered by the coop’s 12V battery via a 5V linear regulator.
There are three sensors:
battery voltage
temperature
door open/closed
Every ten seconds the Pico wakes up, reads the sensors, and sends a JSON packet over Lora, which the house server records and graphs:
