Silicon Labs SI7021-A20-IM

湿度，温度0 ~ 100% 相对湿度I²C

Overview

The SI7021-A20-IM is a monolithic CMOS Humidity and Temperature Sensor with an analogue-to-digital converter, signal processing, calibration data and 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. The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensors are fully interchangeable, with no recalibration or software changes required.
