Product Description:

Product Summary
    Industrial grade resistance type humidity sensor: SYH-2R offers cost effective and convenient humidity measurement.
    While maintaining the attractive features such as no-calibration requirement and high interchangeability of resistive type humidity sensor: SYH-1, SYH-2R widens the scope of applications to home appliances, HVAC, and automotive.
    Coated with patented polymer, SYH-2R can be used in demanding environments (-20°C~85°C) with frequent condensing and chemical vapors.
    SYH-2R can be directly connected to µ-com with ADC or RFC converting resistance changes to either voltage or frequency. It can also be modularized to voltage output with oscillator.
