This is a simple breakout board for the SHT15 humidity sensor from Sensirion. The SHT15 digital humidity and temperature sensor is fully calibrated and offers high precision and excellent long-term stability at low cost. The digital CMOSens Technology integrates two sensors and readout circuitry on one single chip. These sensors are really impressive! Very sensitive and straight forward to use. Board comes assembled and tested with the SHT15.
