Sensirion has launched a high-precision version of the SHT21 digital humidity and temperature sensors – the SHT25 – for applications with stringent accuracy requirements.

The SHT25 precisely measures relative humidity over a range of 0-100 per cent relative humidity (RH) and temperature over a range of -40C to +125C.

It achieves a typical accuracy of 1.8 per cent RH (at 25C) for relative humidity and +/-0.2C for temperature.

For both quantities, the typical tolerance is small even at the limits of the measuring range.

The maximum tolerance is two per cent relative humidity or +/-0.3C over a wide range, as shown by the adjacent figures.

This enables the SHT25 to achieve better accuracy, especially for temperature measurements.

The SHT25 is fully calibrated and exactly matches the other specifications of the SHT21 version.

The reflow-solderable SHT25 has an I2C interface and features stability along with low power consumption.

The new version is available on tape and reel.

A quality management system and individual sensor tracking data are among the features of the SHT25.
