The STS21 is a fully calibrated high accuracy Digital Temperature Sensor with impressive performance. It offers the same superior performance and space saving 3x3mm footprint. It features a different I2C address than the SHT2x and is pin compatible. Therefore it is custom-made for solutions in which temperature measurement is a prerequisite and humidity measurement is optional, as the same hardware can be used for both options. The outstanding accuracy and low power consumption paired with a competitive price make this an ideal solution for applications with high demands on both performance and economy.
