USB Wireless Temperature And Humidity Sensor
Advertisement
This data logger project based on firmware-only USB implementation. There are two part in this project, transmitter and receiver. The transmitter consist of ATTiny45 microcontroller, a SHT11 sensor (digital temperature and humidity sensor) and a hoperf RFM12 868 MHz transceiver module. The transmitter powered by 2 AA cells. While the receiver uses ATMega8 µC and the same RFM12 module. After received data from transmitter wirelessly, It will send the data to PC via USB.
