Humidity and Temperature Sensor - SHT21 (I2C)
CHF 8.63

Stock: 6

The SHT21 humidity and temperature sensor of Sensirion has become an industry standard in terms of form factor and intelligence. Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3x3mm footprint and 1.1mm height it provides calibrated, linearized sensor signals in digital, I2C format.

The SHT21 sensors contain 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 SHT21 can be changed by command (8/12bit up to 12/14bit for RH/T) and a checksum helps to improve communication reliability.


  • Supply voltage: 2.1 - 3.6VDC
  • Low current consumption: 0.15 - 0.4uA (sleep), 200-330uA (measure)
  • Small DFN package of 3x3mm
  • I2C, PWM interface
  • Accuracy: 2% Humidity, 0.3% Temperature
