Humidity sensor


Recommended Posts

According to Sensirion datasheet here SHT31-ARP-B is an analog output temperature and humidity sensor with linearized and calibrated output. To interface it with Arduino you will have to measure the output voltage using an Arduino analog input and then convert the reading to humidity or temperature value based on the linear formulas found on the datasheet. These formulas are depended on the supply voltage of the sensor.

I also found an Arduino library for this sensor here: https://github.com/winkj/arduino-sht you may find it useful.
