What are the types of gas sensors?

Gas sensors are also called Gas Detectors. These sensors are electronic devices that detect and identify different types of gases. They are commonly used to detect toxic or explosive gasses and measure gas concentration.

How does a gas sensor work?

The working of a gas sensor depends upon the concentration of the gas. 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.

How does a smoke sensor module work?

Smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.

What are MQ2 and MQ3 gas sensors?

MQ2 Gas Sensors

MQ2 gas sensors are also called as chemiresistors. It is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide.

MQ3 Gas Sensors

The MQ3 gas sensor is an alcohol sensor which is used to detect the alcohol concentration on your breath. This sensor provides an analog resistive output based on alcohol concentration.

What is the use of gas sensors?

The main purpose of Gas sensors or gas detectors help in detecting the different types of gases in the environment. They are commonly used to detect toxic or explosive gasses and measure gas concentration. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion. They may be used in firefighting.

Are gas sensors compatible with Arduino?

The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, i-butane, propane, methane ,alcohol, hydrogen and smoke.

Where should Gas Sensors be located?

Gas Sensors or Gas detectors should be placed near the floor for vapors or gases three or four times heavier than air. For the detection of lighter than air gases, sensors should be fitted near the roof or ceiling
