LPG Gas detector/Sensor

Hi ,
I am looking for the schematics of LPG gas detector using Figaro's LPG gas sensor TGS 2610, I have the sensor application note but the sample schematics doesnot work properly, please any one out there help me out
thanks :?
 

LPG detector

I am trying the circuit given in the application notes of figaro LPG sensor TGS2610.
But can any body out there help me understand How can I caliberate the sensor,
what is the term "PPM" how this can be achived to see weather the sensor is responding properly to as said PPM in the data sheet.
thanks :p
 
I think calibrating possible only with gas and/or other gas measuring instrument. Send me the application for consideration.
 

the term PPM is parts per million, and is a way of measuing small concentrations.

As for calibration, they talk about test chambers in the PDF's which im assuming release a known concentration. I saw a similar setup for a helium detector calibrator which was a small tank, with a tiny orifice, that was certified to know concentration.

I cant think of any way to calibrate your device with out one of these known constants.

PPM means Parts Per Milion (parts).

To calibrate you can found some spray with a known gas concentration
I'm working fo a firm that make gas detector that make this spray, but I can't sell anything, I'm sorry.
