SHT21 - Digital Temperature And Humidity Sensor (RH&T)

SHT21 - Digital Temperature And Humidity Sensor (RH&T)

Smallest relative humidity sensor for a multitude of applications: "size that inspires"!
The extremely small SHT21 digital humidity and temperature sensor integrates sensors, calibration memory and digital interface on 3 x 3 mm footprint. Additionally the humidity sensor provides electronic read-out of tracking information. The complete over-moulding of the sensor chip – with the exception of the humidity sensor area – protects the fully calibrated and reflow solderable humidity and temperature sensor against external impact and leads to an excellent stability against aging, shock and volatile chemicals.
