The MQ series of gas sensors utilize a small heater inside with an electrochemical sensor these sensors are sensitive to a range of gasses are used at room temperature. MQ135 alcohol sensor is a Sno2 with a lower conductivity of clean air. When the target explosive gas exists, then the sensor's conductivity increases more increasing more along with the gas concentration rising levels. By using simple electronic circuits it converts the charge of conductivity to a corresponding output signal of gas concentration
The MQ135 gas sensor has high sensitivity in ammonia, sulfide, benzene steam, smoke and in other harm full gas. It is low cost and suitable for different applications.
Applications Of MQ 135 Gas Sensor
Air quality monitor
Detection of harmful gases
Domestic air pollution detection
Industrial pollution detection
Portable air pollution detection
