Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air.
When the target combustible gas exists. The sensors conductivity is more higher along with the gas concentration rising.
Please use simple electro circuit, convert change of conductivity to correspond output signal of gas concentration.
MQ-2 gas sensor has high sensitivity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application.

Description

MQ-2 NH3 Gas Sensor Module

The MQ-2 gas sensor is a device that can detect a variety of gases, including flammable gases such as propane and methane, as well as smoke. It is commonly used in applications such as gas leak detectors, safety devices, and industrial control systems. The MQ-2 sensor operates by using a chemical reaction between the target gas and conductive metal oxide to produce a current.

The magnitude of the current is proportional to the concentration of the target gas in the air. The gas sensor can be used to detect a wide range of gas concentrations, depending on the specific type of gas being detected. It is important to note that the MQ-2 sensor is not selective for specific gas and may be triggered by other gases as well. It is recommended to use the MQ-2 sensor with caution and to take appropriate safety measures when working with it.

Applications:

Detect or measure Gases like H2, LPG, CH4, CO, Smoke or Propane
Air quality monitor
Gas leak alarm
Safety standard maintenance
Maintaining environmental standards in hospitals

FAQ

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 sensor 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 ADJUST THE SENSITIVITY OF MQ-2 GAS SENSOR?

In order to adjust the sensitivity of this sensor for the particular type of gas, you need to keep this sensor in the particular gas type you want to detect. Now we have to rotate the potentiometer on the sensor.
Rotate it till the Red LED on the sensor gets ON. If we have to increase the sensitivity, rotate it clockwise, and if we have to decrease the sensitivity we have to rotate it anticlockwise.
When we are rotating this potentiometer basically we are adjusting the threshold value of the sensor. The comparator on this board is constantly checking the threshold value.
Once this threshold gets crossed the digital pin goes high and the LED will turn on. In this way calibrate your sensor, it may take some time but once you calibrate it, it will give you accurate readings.
