Arduino WeatherShield

Project description

Story Overview The WeatherShield by Ethermania.com is a shield that makes Arduino able to read Pressure, Temperature and Relative Humidity. The shield is equipped with three sensors and a PIC12F683 microcontroller programmed with a specific firmware that interfaces with Arduino through a two-line bidirectional synchronous serial connection. The microcontroller is responsible for sampling and averaging the last 8 humidity, pressure and temperature values, providing it to the Arduino in an ASCII readable format expressed in Celsius, hPa and relative % units.
