1. Product introduction:

The product is called resistance type polymer humidity sensor (HR002) and it is a new type of humidity sensor. It has the characteristics of wide sensing range, fast response, high sensitivity, good water resistance, stable and reliable performance, and good consistency.


2.Electrical performance:
1. Rated voltage: 1.5V AC (MAX, sine wave);
2. Rated power: 0.2mW (MAX, sine wave);
3. operating frequency: 50Hz-2000Hz;
4. working temperature: 0 °C -60 °C;
5. working humidity: 20% - 95% RH;
6. Temperature characteristics: ≤0.5%RH/°C
7. hysteresis hysteresis: ≤ 2% RH;
8. Response time: moisture absorption, ≤15S; dehumidification ≤25S;
9. Stability: ≤ 2% RH/year;
10. Humidity detection accuracy: ≤±5%RH;
11. Relative humidity impedance characteristics: (25°C, 1KHZ, AC1V, sine wave)

 

3.Standard verification conditions:

1.In the atmosphere, the temperature is 25°C, the measured frequency is 1KHZ, and the measured voltage is IVAC (sine wave);
2.Make sure to use AC bridge (LCR) when testing, and do not use DC power supply;
3.Use split-type humidity generator (HX-1 type);
4.Measurement line: 1-core shielded wire.
5.Avoid hard objects or fingers touching the surface of components to avoid scratching or staining the wet film;
6.Avoid testing under salt spray, corrosive gases, strong acids, strong bases, organic solvents, alcohol, acetone, etc.
7.Welding conditions (180°C, 3S) For welding, use a low-temperature soldering iron or use tweezers for protection.
8.Recommended Storage Conditions: Temperature 10°C-40°C, Humidity: 20%RH-90%RH.


The specification value is based on the 60%RH humidity change amount; after each test is completed, it should be placed in the normal air of normal temperature and humidity for 24 hours and tested after recovery. The test data are listed in the table.
