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 – an especially important
consideration for battery-operated devices.
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 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.
