This project is a wireless temperature and humidity sensor with USB interface based on obdev’s RemoteSensor example and their firmware-only USB implementation. The main change is the replacement of the analog sensors with a Sensirion SHT11 digital temperature and humidity sensor. The sensor unit consists of an ATTiny45 microcontroller, a SHT11 sensor, and a hoperf RFM12 868 MHz transceiver module. Check details on the link below.
