Sensirion’s SHT25 digital humidity sensor precisely measures relative humidity over a range of 0 to 100% rh and temperature over a range of -40 to +125°C. It achieves a typical accuracy of 1.8% rh (at 25°C) for relative humidity and 0.2°C for temperature.
For both quantities, the typical tolerance is small even at the limits of the measuring range. The maximum tolerance is 2% rh or 0.3°C over a wide range, as shown by the adjacent figures. This enables the new SHT25 to achieve significantly better accuracy, especially for temperature measurements.
The SHT25 is fully calibrated and exactly matches the other specifications of the already successful SHT21 version. Among other things, the reflow-solderable SHT25 has an I2C interface and features outstanding stability along with extremely low power consumption. Like the SHT21, the new version is available on tape and reel. A comprehensive quality management system and individual sensor tracking data round out the features of the SHT25.
