To connect the Winson WSP2110 VOC Gas Sensor to a circuit, you will need to provide two voltage inputs: heater voltage (VH) and circuit voltage (VC). The VH is used to supply the standard working temperature to the sensor and can be either DC or AC power. The VC supplies the detect voltage to the load resistance (RL) and should be DC power.
Here is the basic test circuit for the WSP2110 sensor:
1. Connect Pin 1 and Pin 2 of the sensor to the heater circuit.
2. Connect Pin 3 and Pin 4 of the sensor to the measuring circuit.
3. Connect the VH voltage source to the heater circuit (Pin 1 and Pin 2).
4. Connect the VC voltage source to the measuring circuit (Pin 3 and Pin 4).
5. Place a load resistance (RL) in series with the sensor.
Please refer to the manual for more detailed instructions and information on the sensor's electrical characteristics and specifications.
