Sensirion – SHTW2: Ultra Small Digital Humidity Sensor


The SHTW2 is based on Sensirion’s CMOSens® technology, which offers a complete sensor system on a single chip, consisting of a capacitive humidity sensor, a band-gap temperature sensor, analog and digital signal processing, A/D converter, calibration data memory, and a digital communication interface supporting I2C fast mode. The humidity sensor covers a humidity measurement range of 0% to 100% RH and a temperature measurement range of -30°C to +100°C with a typical accuracy of ±3% RH and ±0.4°C.
