HIH-4000-001

HIH-4000 series humidity sensor 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, the HIH-4000 Series is often ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. RH sensor is a laser trimmed, thermoset polymer capacitive sensing element with on-chip integrated signal conditioning. The sensing element's multilayer construction provides excellent resistance to most application hazards such as wetting, dust, dirt, oils and common environmental chemicals. Typical applications include Refrigeration equipment HVAC (Heating, Ventilation and Air Conditioning) equipment, medical equipment, drying, metrology, battery-powered systems, OEM assemblies.
