MQ6 Fuel Sensor Module

Sensitive material MQ-6 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When there is the environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-6 gas sensor for propane, butane , liquefied petroleum gas sensitivity is high, natural gas and has a good sensitivity. This sensor can detect a variety of flammable gas, is a low-cost sensors for a variety of applications

Suitable for home or industrial LPG ( liquefied petroleum gas ) , butane , propane , LNG ( liquefied natural gas ) detection devices. Excellent resistance to ethanol vapor , smoke interference Module

Features :MQ 6 Gas Sensor Module

  • Using high-quality dual-panel design, with power indicator and TTL signal output instructions;
  • The switching signal having a DO (TTL) output and analog output AO ;
  • TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
  • 0 ~ 5V analog output voltage , the higher the concentration the higher the voltage.
  • Propane , butane , LPG, LNG has a good detection sensitivity.
  • There are four screw holes for easy positioning ;
  • Product dimensions : 32 (L) * 20 (W) * 22 (H)

Description

The MQ-6 Fuel sensor can detect or measure gases like LPG and butane. The MQ-6 sensor module comes with a Digital Pin which makes this sensorĀ to workĀ even and not using a microcontrollerĀ whichĀ turns out to be usefulĀ when youĀ are solely making an attempt to detect one specific gasoline. In relation to measuring the gasoline in ppm the analog pin needs to be used, the analog pin additionally TTL pushed and works on 5V and therefore can be utilized with commonest microcontrollers.

So ifĀ you areĀ looking forĀ a sensor to detect or measure gasses like LPG, or methane with or and not using a microcontroller then this sensorĀ could possibly beĀ the correctĀ alternative for you.

Utilizing an MQ6 gasoline sensor module could be very straightforward. You may both use the digital pin or the analog pin to perform this. Merely energy the module with 5V andĀ you shouldĀ discoverĀ the powerĀ LED on the module to glow and when no gasoline it detected the output LED will stay turned off that means the digital output pinĀ are going to beĀ 0V. Do not forget that these sensors should be stored on for pre-heating time (talked about in options above) earlier than you’ll be able to really work with it. Now, introduce the sensor to the gasoline you need to detect and you must see the output LED to go excessive together with the digital pin, if not use the potentiometer till the output will get excessive. Now each time your sensor will get launched to this gasoline at this specific focus the digital pin will go excessive (5V) else will stay low (0V).

You may as well use the analog pin to attain the identical factor. Learn the analog values (0-5V)Ā using aĀ microcontroller, this worthĀ are going to beĀ instantly proportional to the focus of the gasoline to which the sensor detects. You may experiment with this values and verify how the sensor reacts to completely different focus of gasoline and develop your program accordingly.
