SI7021-A20-YM1

The Si7006/13/20/21/34 devices are Silicon Labs’ latest generation I2C relative humidity and temperature sensors. All members of this device family combine fully factory-calibrated humidity and temperature sensor elements with an analog to digital converter, signal processing and an I2C host interface. Patented use of industry-standard low-K polymer dielectrics provides excellent accuracy and long term stability, along with low drift and low hysteresis. The innovative CMOS design also offers the lowest power consumption in the industry for a relative humidity and temperature sensor. The Si7013/20/21/34 devices are designed for high-accuracy applications, while the Si7006 is targeted toward lower-accuracy applications that traditionally have used discrete RH/T sensors.
