This sensor is working perfectly
Good for school projects. Children get an understanding about a sensor.
The MQ-135 gas sensor module is a device that is used for sensing a range of gases, including ammonia (NH3), sulfur dioxide (SO2), and carbon monoxide (CO). It is based on a metal oxide semiconductor (MOS) gas sensor, which uses a semiconductor material to detect gases.
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 for ammonia, sulfide, benzene steam, smoke, and other harm full gas. It is low cost and suitable for different applications.
