HIH-4021-004

The HIH-4021-004 is a 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 device is often ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. The device delivers instrumentation quality RH (Relative Humidity) sensing performance in a competitively priced, solderable SIP (Single In-line Package). The HIH-4021 is a covered, condensation-resistant, integrated circuit humidity sensor. The RH sensor is a laser trimmed, thermoset polymer capacitive sensing element with on-chip integrated signal conditioning.
