STS21
±0.2°C Digital temperature sensor
A 3x3mm, fully calibrated digital temperature sensor with impressive performance.
Based on the same chip as the successful and industry proven SHT2x family of humidity and temperature sensors, the STS21 offers the same superior performance and space saving 3x3mm footprint. The temperature sensor 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 the STS21 an ideal solution for applications with high demands on both performance and economy.
