What is MQ6 sensor?

Introduction. The MQ6 (LPG Gas Sensor) is a simple-to-use liquefied petroleum gas (LPG) sensor. It can be used in gas leakage detecting equipment in consumer and industry applications,this sensor is suitable for detecting LPG, iso-butane, propane, LNG. Avoid the noise of alcohol, cooking fumes and cigarette smoke.

How does the gas sensor work?

Electrochemical sensors: These are highly sensitive detectors generally used for measuring toxic gases such as carbon monoxide. They work by sensing electrodes in the air and then give off a warning signal using electrical currents. They’re specifically used to measure hydrocarbon gases.

How does LPG gas detector work?

An LPG gas sensor is a one kind of device which is used to sense the presence of a hazardous LPG gas leak in service station, cars, storage tanks and homes. This sensor is attached to an alarm circuit to give an alert to the operators through a buzzer sound in the area where the gas leak is occurring.

How many types of gas detectors are there?

There are four basic types of portable gas sensors: Catalytic combustion • Electrochemical (echem) • Infrared (IR) • Photoionization detectors (PID) When any of these sensors sense gas, the electronics will change the sensor output into a reading on the display showing the level of gas exposure.

What is the use of MQ6 gas sensor?

The MQ6 gas sensor is a sensor that has a fast response to LPG (Liquid Petroleum Gas), is stable and durable and can be used in a simple drive circuit. MQ-6 gas sensors are commonly used in equipment to detect gas leaks in household and industrial activities, which are suitable for detecting LPG, iso-butane, propane.

Which sensor is used to detect LPG?

In this paper, semiconductor sensors are used to detect LPG gas. An MQ6 semiconductor sensor is used. Sensitive material of the MQ-6 gas sensor is SnO2, which has lower conductivity in clean air. When the target combustible gas exists, the sensor conductivity increases along with the rising gas concentration.

Why do we need gas sensor?

Gas sensor, as one of the most important devices to detect noxious gases, provides a vital way to monitor the concentration and environmental information of gas in order to guarantee the safety of production. Therefore, researches on high sensitivity, high selectivity, and high stability have become hot issues.

What is the range of gas sensor?

How is LPG leak detected?

LPG is an odourless gas which settles on the ground level. To detect any leakage, Ethyl Mercaptan is added to it. The LPG Leak Detector is a wall mounted device fitted close to the floor level with an alarm setting at 20% of Lower Explosive Limit.

Which type of gas sensor is best?

Open Path Infrared (OPIR) Industrial Gas Sensors This type of industrial gas detector works best with hydrocarbon gases, silicones, hydride gases, or halogenated hydrocarbons that may be found in large, open areas.

What can set off a gas detector?

Malfunctioning water heater or furnace: Improper ventilation, excess gas flow or other malfunctions could set off your carbon monoxide detector. Obstructed chimney: If fumes can’t escape, they become trapped inside. The carbon monoxide detector senses this and sounds the alarm.

What can the mq6 gas sensor be used for?

The MQ6 Gas Sensor module is useful for gas leakage detection. They are used in gas leakage detecting equipments in home and industry, are suitable for detecting of LPG, iso-butane, propane, LNG, avoid the noise of alcohol, cooking fumes and cigarette smoke.

How does the Grove gas sensor ( mq3 ) work?

As per the data-sheet of the MQ3 sensors, these equations are tested for standard conditions and are not calibrated. It may vary based on change in temperature or humidity. Keep the Gas Sensor in clean air environment. Upload the program below. Then, open the serial monitor of Arduino IDE.

What kind of gas can a gas sensor detect?

The MQ-6 Gas sensor can detect or measure gases like LPG and butane. The MQ-6 sensor module comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas.

What is the digital output pin on a gas sensor?

You can either use the digital pin or the analog pin to accomplish this. Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas it detected the output LED will remain turned off meaning the digital output pin will be 0V.
