metallic oxide, which with high conductivity in clean air. When the ozone gas exists, the sensor_s conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
MQ131 ozone gas sensor has high sensitivity to ozone, and also has sensitivity to strong oxide such as Cl2, NO2 &etc. It responses oppositely to organic interference gases. Features
It has good sensitivity to ozone in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc. _ Detection Gas: Ozone, O3
_ Detection Range: 10-1000ppm Ozone
_ Application: domestic ozone concentration alarm <<

_ Application: Domestic gas leakage alarm Sensitive material of MQ-8 gas sensor is SnO2, which with lower conductivity in clean air. When hydrogen gas exists, the sensor_s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
MQ-8 gas sensor has high sensitivity to hydrogen gas, also has anti-interference to other gases. This sensor can detect hydrogen, especially city gas. It is a kind of low-cost sensor for kinds of applications.
Applications :
It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector. <<

_ Application: domestic gas leakage alarm, portable gas detector Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target flammable gas exist, the sensor_s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
MQ-5 gas sensor has high sensitivity to butane, propane, methane and can detect methane and propane at the same time. It also can detect kinds of flammable gases, especially LPG(propane).It is a kind of low_cost sensor for many applications.
