A low-cost member of the Sensirion’s SH2x family, the SHT20 humidity and temperature sensor with a typical accuracy of 3% RH is distinguished by such features as high long-term stability, full calibration and both digital and analog interfaces. It is based on the CMOSens technology, which enables high production volumes with good value for money. Despite being significantly less costly than its predecessor, depending on purchase volume, the sensor offers a temperature measurement accuracy of ±0.4 °C and a measuring range of -40 to +120 °C. With a 3x3-mm footprint and 1.1-mm profile, it is one of the smallest sensors in its class. These properties make it the first choice for many applications.
