The Si701x/2x devices are Silicon Labs' 2nd generation family of 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.
