Temperature & Humidity Sensor

Haechitech`s Temperature & Humidity Sensors ICs are a state of the art sensors utilized proven techniques for measuring humidity using polymer dielectric film along with CMOS mixed signal integrated circuits. It provides fully calibrated digital output(I2C, PWM, PDM) and analog output as well. In particular, its analog output allows for easy integration without the need for additional calibration/component.

The resolution can be changed by command (8/12bit up to 12/14bit for RH/T). Every sensor is individually calibrated and tested and the lot identification is printed on the sensor.
