This is a breakout board of the famous sensor Sensirion SHT1x.
SHT1x is Sensirion’s family of surface mountable relative humidity and temperature sensors.
The sensors integrate sensor elements plus signal processing on a tiny foot print and provide a fully calibrated digital output.
A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap sensor.
The applied CMOSens® technology guarantees excellent reliability and long term stability.
