Description: Specifications: 1pcs MQ131 ozone sensor oxygen gas sensor high concentration The gas sensitive material used in the MQ131 sensor is a semiconductor metal oxide with high conductivity in clean air. When there is ozone in the environment where the sensor is located, the conductivity of the sensor decreases as the concentration of ozone gas in the air increases. Using a simple circuit, the change in conductivity can be converted into an output signal corresponding to the gas concentration. MQ131 has high sensitivity to ozone, and also has a certain sensitivity to strong oxidizing gases such as chlorine and nitrogen dioxide, and reacts in the opposite direction to ozone for organic interference gases. The ozone sensor has good sensitivity to ozone in a wide concentration range, and has the advantages of long life, low cost, and simple driving circuit. It is widely used in household ozone concentration exceeding standard alarms, industrial ozone concentration exceeding alarms and portable ozone concentration detectors.
