MQ-135 gas sensor Module
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.

1. What are gas sensors? How do they work?
- Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration. Gas sensors detect the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated.
2. How to use MQ-135 Sensors to detect gases?
- You can either use the digital pin or the analog pin to do this. Simply power the module with 5V and you should notice the power LED on the module is low when no gas it detected the output LED will remain turned off meaning the digital output pin will be 0V.
- Remember that these sensors have to be kept on for pre-heating time before you can actually work with it. Now, introduce the sensor to the gas you want to detect and you should see the output LEDs them go high along with the digital pin, if not use the potentiometer until the output gets high. Now every time your sensor gets introduced to this gas at this particular concentration the digital pin will go high (5V) else will remain low (0V).
- You can also use the analog pin to achieve the same thing. Read the analog values (0-5V) using a microcontroller, this value will be directly proportional to the concentration of the gas which the sensor detects.
3. What is MQ135 used for?
- The alcohol sensor detects the presence of alcohol gas in the air and outputs an analog voltage. The MQ135 gas sensor senses gases such as ammonia, nitrogen, oxygen, alcohol, aromatics, sulfides and smoke. The MQ 135 sensor can be implemented to detect smoke, benzene, vapors, and other hazardous gases. It can detect various harmful gases. It can be used for air quality monitoring, noxious gas detection, home air pollution detection, industrial pollution detection, portable air pollution detection, etc.
