Digital temperature sensor measures only 3x3mm
This makes the sensor suitable for use in applications where only very limited space is available. It also delivers outstanding performance and remarkably high accuracy of ±0.22 °C over the temperature range of 5 to 60°C, combined with very low power consumption.
The STS21 is pin and protocol compatible with Sensirion’s standard SHT21 humidity sensor, but it has a different I2C address. This allows the STS21 to be used as an alternative to the SHT21 in applications where temperature measurement is required and humidity measurement is optional, since the same hardware can be used with both sensors. The STS21 temperature sensor is fully calibrated, provides a digital output, and is very competitively priced. It therefore fulfills the stringent requirements of many applications in terms of both performance and cost effectiveness.
