Swiss Sensirion digital temperature sensor
The STS21 temperature sensor and the SHT2x temperature and humidity sensor are based on the same chip design, offering superior performance, with the same compact size of only 3x3mm. The temperature sensor has a different I2C address from the SHT2x and is pin-to-pin compatible. Therefore, the STS21 is suitable for applications where temperature is a mandatory parameter and humidity is optional. Since the hardware is identical, users do not need to modify their hardware design.
