MQ-5 Natural/ LPG Gas Sensor Module

The MQ5 gas sensor is a metal oxide semiconductor (MOS) type gas sensor, also known as a chemiresistor. MQ5 is used to detect flammable gases such as LPG, natural gas, coal gas, and propane. The sensor has a high sensitivity to these gases, and can detect them in concentrations as low as 200 ppm.

The MQ5 gas sensor works by measuring the change in resistance of the sensing material when it comes into contact with a gas. The sensing material in the MQ5 sensor is tin dioxide (SnO2), which has a low resistance in clean air. When a flammable gas is present, the tin dioxide reacts with the gas and its resistance increases. The amount of resistance increase is proportional to the concentration of the gas.

The MQ5 gas sensor module is easy to use. It can connect to a microcontroller or other electronic device using the analog output. The sensor can use to detect the presence of flammable gases.

The MQ-5 gas sensor has an input voltage of 5V. This means that it must connect to a power supply that provides 5V of DC power. The sensor also has a heater that requires 100mA of current to operate. This heater is used to heat the sensor to a specific temperature, typically around 300°C. This improves the sensor’s sensitivity to gases.

If the MQ-5 gas sensor not connected to a power supply that provides 5V of DC power, it will not work properly. The sensor will not be able to heat up to the required temperature, and its sensitivity to gases will be reduced.

It is important to note that the MQ-5 gas sensor is not compatible with 3.3V power supplies. If the sensor connect to a 3.3V power supply, it will damage.

Features : –

MQ5 gas sensor module is a small, self-contained unit that includes the sensor, a heater, and an analog output. The sensor made of tin dioxide (SnO2), which is a semiconductor that reacts with gases. The heater use to heat the sensor to a specific temperature, which improves its sensitivity. The analog output is proportional to the concentration of gas in the air.
