The SHT3x combines the strengths of the SHT1x, the SHT2x and the advanced SHTC1 series in a single product. It includes a user programmable alert function, where the sensor can be used as a humidity and temperature sensor; and an analogue ratiometric voltage output. The company says it is the first fully calibrated and linear digital/analogue humidity and temperature sensor. The SHT3x series combines multiple functions and various interfaces (I²C, voltage out) with a user-friendly, very wide operating voltage range (2.4 to 5.5 V). SHT3x is based on the CMOSens Technology, which allows a high production volume at a favourable price/performance ratio. The technology enables a small footprint of 2.5 x 2.5 mm with a height of 0.9 mm. It is one of the smallest humidity sensors for applications over 2.4 V.
