HYT 271 Digital Humidity Element With I2C Interface

HYT 271 Digital Humidity Element With I2C Interface

The HYT 271 combines the advantages of a precise, capacitive humidity sensor with the high functionality of an ASIC. Integrated signal processing provides relative humidity and temperature over the I2C compatible interface as digital values. The module is factory calibrated and any further alignment by the user is not necessary.  Both linearity and temperature drift are corrected by on chip calibration, providing excellent accuracy over a wide range of temperature and humidity.
