SENSIRION  SHT21  Humidity Sensor, 2 %, 3 V, 0% to 100% Relative Humidity, DFN, 6 Pins, 8 s

Product Overview

The SHT21 is a surface mount Temperature and Humidity 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 3 x 3mm foot print and 1.1mm height it provides calibrated, linearized sensor signals in digital, I²C format. The SHT2x sensor 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.
