Product description:

The gas sensing material used in the MQ131 ozone sensor is a semiconducting metal oxide with a high electrical conductivity in clean air. When ozone is present in the environment in which the sensor is located, the conductivity of the sensor decreases as the concentration of ozone gas in the air increases. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.

The MQ131 ozone sensor has high sensitivity to ozone, and has certain sensitivity to strong oxidizing gases such as chlorine and nitrogen dioxide, and reacts organic interference gas in the opposite direction to ozone.

Features:

This product has good sensitivity to ozone in a wide concentration range, and has the advantages of long life, low cost, and simple driving circuit.

Application:

It is widely used in household ozone concentration exceeding alarms, industrial ozone concentration exceeding alarms and portable ozone concentration detectors.

Note:The figure above shows the basic test circuit for the MQ131 sensor. The sensor requires two voltages to be applied: heater voltage (VH) and test voltage (VC). The VH is used to provide a specific operating temperature for the sensor, either DC or AC. The VRL is the voltage across the load resistor (RL) of the sensor in series. VC is the voltage for testing the load resistor RL and requires a DC power supply.
