Sensirion has launched a high-precision version for applications with stringent accuracy requirements – the SHT25 which
precisely measures relative humidity over a range of 0 to 100% RH and temperature over a range of -40 to +125°C.
The sensor 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% relative humidity or ±0.3°C over a wide range. 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 SHT25 can be reflow-soldered and it has an I2C interface and features outstanding stability along with extremely low power consumption. As with the SHT21, the new version is available on tape & reel.
