ATK-MQ6-GAS SENSOR

GAS SENSOR

Overview

Sensitive material of MQ-6 gas sensor is SnO2, which with lower conductivity in

clean air. When the target combustible gas exist, The sensor’s conductivity is more

higher along with the gas concentration rising. Please use simple electro circuit,

Convert change of conductivity to correspond output signal of gas concentration.

MQ-6 gas sensor has high sensitivity used in to carbon monoxide, also could be

used to Methane and other combustible steam, it is with low cost and suitable for

different application.

Features

Operating voltage: 5V Provide both digital and analog output Adjustable sensitivity Output LED indicator Compatible with Arduino and Microcontroller TTL Compatible Onboard holes for easy installation

Applications

Consumer electronics

Industrial Combustible gas detector

Portable gas detector

Pin Diagram

Pin Pin Name

Pin Name

+5V I/P Regulated 5V supply input

GND GND Ground level of power supply

DO O/P Digital Output to external devices

AO O/P Analog Output to ADC

Note: Initially the sensor gives high output so power on the sensor for 15minites

because it needs initially heating voltage then and then it gives proper output.

More info refer the datasheet for the same.

Recommend separate power supply because its required more current to heat.
