Abstract:
This paper presents the design and functionality of a methane (CH4) concentration measurement system, based on a virtual instrumentation (VI) solution implemented using National Instruments’ LabVIEW. It contains a semiconductor type dedicated gas sensor, specific conditioning circuitry and a software program running on a portable computer. An important feature of the proposed implementation is the possibility to transmit calculation results and receive control commands from a mobile phone with internet connectivity. Other features include data logging of concentration parameters and statistical calculations. The instrumentation represents a cost effective solution due to software/hardware adaptability and can be easily extended for monitoring other gases. Experimental results which illustrate the operation of the system in CH4 contaminated environments are also presented.
