Project Questions / Guidelines / MQ5 LPG gas sensor
« on: July 05, 2012, 05:31:56 AM »
Hello Everyone,

I am using MQ5 Gas sensor. I want to calibrate for detecting LPG gas leakages. What resistor shall i use in r1 in http://wiring.org.co/learning/basics/airqualitymq135.html

Also, please tell what does output show? What kind of value is it?
What is ppm level when LPG gas leakage in house is dangerous?

Thank you.
