Mq 6 module circuit used in gas leakage alarm

hellow sir !

           i am doing a small project on gas leakage alarm ! In the circuit i need a gs module . now i want to design it on my own . so i want you to help me out in havin the exact circuit model . Now this is the circuit model of gas leakage alarm

but am unable to find the way towards mq6 sensor module. Do I have an easy way instead of making the whole circuit of mq6 module? if yes please help .

In order to create your alarm, you could use the MQ6 sensors (RB-See-49), a buzzer (RB-See-52) and a microcontroller such as Arduino (RB-Ard-18). You can also use an IO expansion shield to easily connect the sensor to the Arduino board (RB-See-40)
