Description

MQ-2 Gas Sensor Module

The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer

MQ-2 gas sensor using gas-sensitive material is to be clean air in the lower conductivity of tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the conductivity of the sensor with an increasing concentration of combustible gas in the air increases.

Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas. MQ-2 gas sensor's higher sensitivity to liquefied petroleum gas, propane, hydrogen, detection of gas, and other combustible vapours are ideal. This sensor can detect a variety of flammable gas, and is a low-cost sensor for many applications.

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.
