Abstract:

Demand of strict environmental safety norms in mines, industries leads to the development of smart sensor systems for monitoring the explosive and toxic gases like methane (CH/sub 4/) and carbon monoxide (CO). In the present work a wireless integrated CH/sub 4/ and CO gas sensor with a unique transmission scheme has been proposed. It detects CH/sub 4/ & CO gas and generates frequency modulated (FM) signal in two distinct frequency bands in the range of 2.5823 GHz to 2.5542 GHz for CH/sub 4/ concentration from 1% to 2.5% in air and 2.4854 GHz to 2.404 GHz for CO concentration from 50ppm to 300ppm. Also it transmits the generated FM signal through antenna. The receiver section demodulates the signal and displays the gas concentration.
