How to demonstrate functionality of a mq6 gas sensor

[project1]

Hello,

I'm using a mq6 gas sensor interfaced to a pic18f4550 to detect gas and give an alarm. I need to demonstrate this functionality in a place where its not possible to take a gas cylinder with me. Can someone please give me some idea on how to demonstrate the working of the project?

:idea: Cigarette Lighters or A refill pack for the same! :-D

When using this components, sensitivity adjustment is very necessary. When accurately measuring, the proper alarm point for the gas detector should be determined after considering the temperature and humidity influence.

When I check with a multimeter, it shows that the heater pins are shorted. Does this mean that my sensor's heater is damaged?

No. It will show some resistance.

Heater Resistance is 33 Ohm between H-H pins. Oneside of H is connected with one A or B
