Dexter - Temperature, Humidity & Pressure Sensor [Discontinued] _ARD_CASE_YUN 42kHz Ultrasonic sensorTemperature Humidity Pressure Sensor for a Raspberry Pi Robot! The Temperature Humidity Pressure Sensor can be mounted to Dexter Industries robots like the GoPiGo, GrovePi, and BrickPi . It detects temperature, humidity and pressure from the surrounding environment. For this reason, it is often called a weather sensor. The sensor will measure atmospheric pressure between 30kPa to 110kPa, relative humidity and temperature. It comes with a grove cable
