Si7021-A20-GM

Relative Humidity and Temperature Sensors

The Si7021-A20-GM digital relative humidity and temperature sensor integrates humidity and temperature sensor elements, an analog-to-digital converter, signal processing and an I2C interface in a single chip. The Si7021-A20-GM has a temperature accuracy of ±0.4 °C and a relative humidity accuracy of ±3%. The innovative CMOS design also offers the lowest power consumption in the industry for a relative humidity and temperature sensor. With full factory calibration, the Si7021-A20-GM requires no additional RH/temperature calibration during PCB assembly.
