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 :?
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
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.
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.
