SI7022 - HUMIDITY/TEMPERATURE SENSOR

Download the SI7022 datasheet PDF. This datasheet also covers the SI7022-A20 variant, as both devices belong to the same humidity/temperature sensor family and are provided as variant models within a single manufacturer datasheet.

General Description

The Si7022 Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and a PWM output.

The PWM output may be filtered to produce an analog voltage output.
