MQ2 Flammable Gas and Smoke Sensor

MQ2 Flammable Gas and Smoke Sensor

The MQ2 Flammable Gas and Smoke Sensor is a practical tool for detecting gas leaks in both residential and industrial settings. It has the ability to detect a variety of gases, such as LPG, i-butane, methane, alcohol, Hydrogen, and smoke. Its quick response time allows for prompt measurements to be taken. Additionally, the sensitivity can easily be adjusted using the potentiometer.

The MQ2 Flammable Gas and Smoke Sensor has a wide detection range of 200 to 10000ppm for various gases. Specifically, it is highly sensitive to Propane, Hydrogen, methane and LPG.

The MQ series employs a compact heater and electro-chemical sensor. Capable of detecting various gases with precision, these sensors are commonly utilized indoors at standard room temperatures.

The SnO2 material in MQ2 Gas sensor is highly sensitive and has lower conductivity in clean air. As the gas concentration increases, the sensor’s conductivity also rises. This makes MQ2 sensor ideal for detecting various combustible gases, including Methane. Additionally, its low cost makes it suitable for a range of applications. For instance, it can be incorporated into a wireless Gas leak detector for home security purposes.

The characteristics of MQ2 Flammable Gas and Smoke Sensor include:

• Strong reaction to Propane, smoke, Hydrogen, LPG, CO, alcohol, Smoke.
• MQ2 Flammable Gas and Smoke Sensor boasts a fast response time of under 10 seconds, along with high sensitivity and a stable, long life. To keep the sensor operating effectively, it is necessary to connect 5 volts across the H pins. Additionally, supplying 5 volts to either the A or B pins will result in an analog voltage being emitted on the corresponding pins. Adjusting the resistive load between the output pins and ground determines the sensitivity of the detector. Its uses include detecting gas leaks, ensuring fire and safety precautions, sounding off gas leak alarms, or serving as an industrial combustible gas detector.
