Product Overview

The SI7020-A20-IM1 is an 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.
  • Precision relative humidity sensor - ±4% RH (maximum) at 0-80% RH
  • 0 to 100% RH Operating range
  • Low power consumption - 150µA Active current
  • Low power consumption - 60nA standby current
  • Integrated on-chip heater
