HIH-4021-004 Moisture sensor, analogue, filter, calibrated, SIP

The HIH-40104020/4021 series humidity sensors were designed specifically for high volume 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 200 µA, the HIH-4010/4020/4021 series is often ideally suited for low-drain, battery-operated systems. Seamless interchangeability of sensors reduces or eliminates the cost of calibration by the original manufacturer. Individual sensor calibration data is also available. The HIH-4010/4020/4021 series delivers instrumentation-quality relative humidity sensing performance in a competitively priced, solderable SIP (single in-line enclosure). The HIH-4010 is an uncovered integrated humidity sensor, the HIH-4020 is a covered integrated circuit humidity sensor, and the HIH-4021 is a covered, condensation-resistant, integrated circuit humidity sensor. All three products are available in two lead space configurations. All three products are available in two lead space configurations. The humidity 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. Both products are available in two lead spacing configurations, as well as with or without calibration and data printouts.

- Moulded thermoset plastic housing - Near-linear voltage output vs % RH - Laser trimmed interchangeability - Increased accuracy, fast response - Fast response time - Stable performance with little deviation - Chemically resistant
