IST Hygrochip series digital humidity sensors combine the advantages of a precise capacitive humidity sensor element with the high integration density and functionality of an ASIC. The integrated signal processor receives the measured data and directly delivers the physical parameters of relative humidity and temperature over an I2C compatible interface. Both nonlinearity and temperature dependence are corrected ‘OnChip’ by computation, improving accuracy (±1.8% rH, ±0.2C) for a wide range of applications.
