Digital Humidity/Temperature Modules from IST AG

Innovative Sensor Technology: Mechanically robust, chemical and condensed water proof sensing area, the digital HYT module offers a wide application window and an optimal price performance ratio. Precisely calibrated, the HYT modules deliver an outstanding accuracy and an excellent long term stability even at high humidity - ideal for sophisticated mass applications, industrial handheld devices and precise humidity transmitters. Like all representatives of the HYT family, the module combines the advantages of a precise, capacitive polymer humidity sensor with the high integration density and functionality of an ASIC. The signal processing integrated in the HYT module completely processes the measured data and directly delivers the parameters of relative humidity and temperature over the I²C compatible interface as digital values. The module is precisely calibrated and is therefore fully interchangeable without adjustment.
