The SHTC3 digital humidity sensor builds on the success of the proven SHTC1 sensor. Thanks to a broader supply voltage range (1.62 – 3.6 V) and higher accuracy (+-2% RH, +-0.2C) than its predecessor, it enables greater flexibility.
Sensirions CMOSens Technology offers a complete sensor system on a single chip, consisting of a capacitive humidity sensor, a bandgap temperature sensor, analog and digital signal processing, A/D converter, calibration data memory, and a digital communication interface supporting I2C fast mode. The small 2x2x0.75mm DFN package enables applications in even the most limited space. The sensor covers a humidity measurement range of 0 to 100% RH and a temperature measurement range of -40C to 125C with a typical accuracy of +-2% RH and +-0.2C. The broad supply voltage of 1.62 V to 3.6 V and an energy budget below 1 uJ per measurement make the SHTC3 perfectly suited to mobile or wireless applications powered by battery.
