HYT 221 (IST INNOVATIVE SENSOR TECHNOLOGY)

The HYT 221 from IST Innovative Sensor Technology is a Hygrochip digital humidity and temperature module used in critical application areas. This is a precise, capacitive polymer humidity sensor with the high integration density and functionality of an ASIC. The signal processing integrated in the sensor completely processes the measured data and directly delivers the physical parameters of relative humidity and temperature over the I2C compatible interface as digital values. The round stainless steel casing can easily be fitted into housing openings and can be sealed against the wall with the use of an O-ring. Combined with the waterproof metal filter, it results into an assembly that is splash water proof and enables a sealed housing construction while providing a high dynamic responsiveness. Precisely calibrated, the HYT 221 delivers an accuracy of ±1.8% RH and ±0.2°C.
