SHT3x Digital and Analog Humidity Sensors

Sensirion's digital SHT3x humidity sensor series takes sensor technology to a new level and as the successor of the SHT2x, it is destined to become the next industry standard in humidity sensing. The SHT3x humidity sensor series consists of a low-cost version with the SHT30 humidity sensor and a standard version with the SHT31 humidity sensor. The SHT3x humidity sensor series combines multiple functions and various interfaces (I²C, analog voltage output) with a user-friendly, very wide operating voltage range (2.4 V to 5.5 V). The SHT3x humidity sensor is available in both large and small volumes.

The SHT3x builds on a completely new and optimized CMOSens^® chip, which allows for increased reliability and improved accuracy specifications. The SHT3x offers a range of new features, such as enhanced signal processing, two distinctive and user-selectable I²C addresses, an alert mode with programmable humidity and temperature limits, and communication speeds of up to 1 MHz.
