Above all this sensor impresses with a excellent price/performance ratio.
The basic accuracy of ±2% RH and ±0.3 °C is higher than the accuracy of most competitor products, with signifi cantly better chemical resistance and long-term stability. Despite the miniaturised dimensions of only 4x6x1.9 mm, this sensor offers a measuring range of 0...100% RH as well as -40...125 °C and thus offers a wide range of applications. The integrated signal processing directly supplies the physical values of relative humidity and temperature as digital values a I2C-interface.
