Pressure
The SparkFun Weather Shield is an easy-to-use Arduino shield that grants you access to barometric pressure, relative humidity, luminosity and temperature. There are also connections on this shield to optional sensors such as wind speed, direction, rain gauge and GPS for location and super accurate timing. The Weather Shield utilizes the Si7021 humidity/temperature sensor, the….

Read moreThe WeatherShield1 is able to read temperature, pressure and humidity values from the environment. It’s equipped with a microcontroller that manages sampling and performs moving average on the last 8 samples. It’s connected to the Arduino board though a synchronous bidirectional serial protocol similar to what was implemented in the MM5450 LED driver.
