Product Overview

The SHT21 is a Humidity and Temperature Sensor IC features low power consumption and excellent long-term stability. The SHT2x sensors contains a capacitive type humidity sensor, a band gap temperature sensor and specialized analog and digital integrated circuit - all on a single CMOSens® chip. This yields in an unmatched sensor performance in terms of accuracy and stability as well as minimal power consumption. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip - which can be read out by command. Furthermore, the resolution of SHT2x can be changed by command (8/12-bit up to 12/14-bit for RH/T) and a checksum helps to improve communication reliability.
  • Fully calibrated
  • Digital output, I²C interface
  • 3.2µW (at 8 bit, 1 measurement/s) Energy consumption
