Sensirion launches first digital temperature sensor

Following the successful market launch of the SHT2x family of humidity and temperature sensors, Sensirion is now launching a sensor designed exclusively for temperature measurement. The new STS21 temperature sensor is based on the same chip as the SHT2x family and is housed in a tiny DFN package measuring only 3x3 mm. This makes the sensor ideal 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 – 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.
