Digital Humidity Sensors (RH&T) - Overview

Sensirion’s family of relative humidity and temperature sensors has made it to be an industry standard - mainly due to high integration (CMOSens® Technology) and tiny size. The sensors provide digital and fully calibrated output which allows for easy integration and provides from doing any additional calibration. The excellent long term stability has been very well perceived and the cutting edge low energy consumption is unachieved and makes them the right choice for any remote application.

The sensors are provided in two packaging types: SMD type - the SHT1x series - and pin type - the SHT 7x series. The SMD types are reflow solderable while pin type sensors are used for devices where flexible integration is crucial or easy exchange is necessary. The two series are subdivided according to different accuracy levels of humidity reading.

Any application deserves a specific type - the following table shall help to make the right choice. For detailed specification please refer to respective datasheets.

Humidity Sensor		Packaging	Max. RH tolerance*	Max. T tolerance*	Sensor Output
SHT10		SMD	±4.5%RH	±0.5°C	Digital Sbus
SHT11		SMD	±3%RH	±0.4°C	Digital Sbus
SHT15		SMD	±2%RH	±0.3°C	Digital Sbus
SHT21		DFN	±3%RH	±0.4°C	I2C, PWM, SDM
SHT71		Pins	±3%RH	±0.4°C	Digital Sbus
SHT75		Pins	±1.8%RH	±0.3°C	Digital Sbus
