Industrial Grade Waterproof Humidity Sensor Humidity Module
Applicable to different industries
CHR01 series is an industrial-grade impedance polymer humidity sensor (humidity sensitive resistor), which uses functional polymer film to coat on the ceramic substrate with conductive electrode to form a sensitive component whose impedance changes logarithmically with relative humidity.
The conductive mechanism is that the presence of water molecules affects the mobility of conductive ions in the polymer film.

temperature, and the component shell needs to be made separately.
Precautions for using the product
1. Do not use DC power supply for components. Please use bridge impedance LCR test equipment when testing.
2. Avoid hard objects or fingers directly contacting the surface of the element to avoid scratching or polluting the sensitive film.
3. The temperature shall not be too high during welding (<180ºC, 2s film surface), and low temperature soldering iron or tweezers shall be used for protection.
4. Try to avoid direct use in the following environment: salt mist, corrosive gas: strong acid (sulfuric acid, hydrochloric acid), strong alkali, organic solvent (alcohol, acetone, etc.).
5. Recommended storage conditions: temperature 10ºC-40ºC, humidity 20%RH-60%RH.
