HIH-4010/4020/4021 Series Humidity Sensors DESCRIPTION The HIH-4010 is an uncovered integrated humidity sensor, the The HIH4021 Series Humidity Sensors are HIH-4020 is a covered integrated circuit humidity sensor, and designed specifically for high volume OEM (Original Equipment the HIH-4021 is a covered, condensation-resistant, integrated Manufacturer) users. circuit humidity sensor. All three products are available in two lead space configurations. Direct input to a controller or other device is made possible by this sensor’s near linear voltage output. With a typical current The RH sensor is a laser trimmed, thermoset polymer draw of only 200 µA, the HIH-4010/4020/4021 Series is often capacitive sensing element with on-chip integrated signal ideally suited for low drain, battery operated systems. conditioning. Tight sensor interchangeability reduces or eliminates OEM The sensing elements multilayer construction provides production calibration costs. Individual sensor calibration data excellent resistance to most application hazards such as is available. wetting, dust, dirt, oils and common environmental chemicals. Both products are available in two lead spacing configurations, The HIH-4010/4020/4021 Series delivers instrumentation- as well as with or without calibration and data printouts. quality RH (Relative Humidity) sensing performance in a competitively priced, solderable SIP (Single In-line Package). FEATURES POTENTIAL APPLICATIONS • Molded thermoset plastic housing
