“This project is based on obdev’s RemoteSensor and their firmware only USB implementation, the main change is the replacement of the analog sensors with a SHT11 digital temperature and humidity sensor. The sensor unit consists of an ATTiny45 MCU, a SHT11 sensor, and a hoperf RFM12 868 MHz transceiver module. It is powered by 2 AA cells and is expected to give >1 year of battery life.”
