The Si7021 I2C 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
- an I2C Interface.
The Si7021 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature, in a number of industrial and consumer applications.
Applications of Si7021 include:
- respiratory therapy,
- mobile phones and tablets,
- white goods,
- indoor weather stations,
- asset/goods tracking,
- automotive climate controls, and
- micro-environments/data center monitoring.
