Autonomous greenhouse gas measurement system for analysis of gas migration on landfill sites

摘要

This paper describes the design, development and\udvalidation of an autonomous gas sensing platform\udprototype for monitoring of the greenhouse gases, methane\ud(CH4) and carbon dioxide (CO2). The deployment\udundertaken for validation of the developed prototype\udmonitored landfill gas migration to perimeter borehole\udwells on a landfill site. Target gas concentrations were\udcaptured via infrared gas sensors tuned for each target gas\udand data reported to an offsite data collection point at 12\udhour intervals. This bespoke platform and the\udaccompanying data recording and interface software\udprovide a flexible alternative to the presently employed\udlabor intensive, manual monitoring routines. This\udsuccessful trial brought about a change in the management\udof the trial sites gas extraction system.
