HIH-4031-001

HIH-4031-001 is a series humidity sensor. It is designed specifically for high volume OEM (original equipment manufacturer) users. Direct input to a controller or other device is made possible by this sensor’s near linear voltage output. With a typical current draw of only 200μA, this device is often ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. Individual sensor calibration data is available. It delivers instrumentation-quality RH (relative humidity) sensing performance in a competitively priced, solderable SMD. It is used in applications such as refrigeration equipment, HVAC (heating, ventilation and air conditioning) equipment, medical equipment, drying, metrology, battery-powered systems, OEM assemblies.
