Sensor calibration help (with pay)

Hello all.

I would like to adjust a couple of gas sensors that I have, but I can't find sufficient information. If anyone is interested and has experience in the MQ sensors let me know. I want to get specific properties from each sensor (based on the technical data sheets), and calibrate them to display Rs/Ro and ppm values.

Price negotiable - however, I estimate 4 hours of work with 40 euros per hour.

I also suggest do the sessions via Skype and TeamViewer (remote access).
