    HIH-4010/4020/4021 Series Humidity Sensors

    DESCRIPTION of Humidity Sensor HIH4010/4020/4021 Series
    The HIH-40104020/4021 Series Humidity Sensors are 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 200 uA, the HIH-4010/4020/4021 Series is often ideally suited for low drain, battery operated systems.

    FEATURES of humidity sensor HIH4010/4020/4021 Series
    1) Near linear voltage output vs %RH
    2) Laser trimmed interchangeability
    3) Low power design:Fast response time
    4) Enhanced accuracy
    5) Stable, low drift performance: Chemically resistant
    6) Accuracy (best fit straight line): -3.5 ~ +3.5 % RH
    7) Hysterisis: 3 % RH; Repeatability: +/-0.5 % RH .
    8) Settling time: 70 ms; Response time (1/e in slow moving air): 5 s .
    9) Voltage supply :4 ~5.8 Vdc; Current supply:200 500 uA .
    10) Voltage output (1st order curve fit) VOUT=(VSUPPLY)(0.0062(sensor RH) + 0.16), typical at 25 oC

    APPLICATIONS of humidity sensor HIH4010/4020/4021 Series
    1) Refrigeration equipment
    2) HVAC (Heating, Ventilation and Air Conditioning) equipment
    3) Medical equipment
    4) Drying
    5) Metrology
    6) Battery-powered systems
    7) OEM assemblies
