Connect the gas sensor to gsm sim900

hi guys I am a beginner in arduino ...
i want Connect the gas sensor to gsm sim900
if gas sensor read more than 500 send sms to phone //
i want code please .. :cry:

I think you'll need to include an Arduino in that mix and connect the sensor and the SIM900 to that?

Take a look at the link in my signature, it should give some hints.

of course i have arduino uno and connect the gsm on the arduino and i tested it its run

any replay

If we knew what gas sensor you had in mind we might be able to offer more advice.

When I say 'we' I mean other people on the forum as I wouldn't know a gas sensor if I had one in front of me.

like these ..

help please

What have you tried?
Have you managed to get the sensor working?
Do you have a link to the sensor?

Here is a datasheet for a similar sensor from Sparkfun https://cdn.sparkfun.com/datasheets/Sensors/Biometric/MQ-8%20Ver1.3%20-%20Manual.pdf
