How to calibrate a MQ4 methane gas sensor?

[salman.]

Hi everyone, I would like to know if someone has used this MQ4 methane gas sensor by HANWEI electronics. If so how do you calibrate it for lets say 5000ppm of methane(natural gas) in Air?

need help calibrating it,

thanking you all in anticipation for your precious time and help,
salman.

Like every gas sensor, I suppose it will be calibrated by making a calibration mixture.

so how do I make a calibration mixture of methane and air ? I do not have an expensive calibration equipment or setup. what do you suggest i do to calibrate the sensor without using that expensive equipment?
