General Description

The Si7015 I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-todigital converter, signal processing, calibration data, and an I2C Interface.

The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low drift and hysteresis and excellent long term stability.

Each unit is factory-calibrated, and the calibration data is stored in the onchip non-volatile memory.
