#Tiny Weather

Tiny Weather is a weather station with an e-paper display. It works with an arbitrary number of wireless probes that measure ambient temperature, humidity and pressure. Each probe is powered by two AA batteries with an eight-month battery life or with a mains power supply for uninterrupted operation. The name Tiny Weather comes from ATtiny microcontrollers that power the probes.
