This project describes how to connect the ELV FS20 Weather data receiver to the RasPi

The ELV Weather Data and FS20 Receiver is sold with 2 PCBs, which can to be soldered to the PCB from this project. The RasPI can communicate via UART to the receiver


Optionally it is possible to connect the SparkFun BMP180 barometric sensor to the I2C bus.


It is possible to read all data via Python Script.


Possible usage:

- Private Weather Station

- Home Automation Server


My Weather Station is currently connected to two sensors:

- KS 300 Sensor for Temperature, Humidity, Rain and Windspeed

- Temperature and Humidiy Sensor
