Abstract

In this paper an inexpensive, portable tool was designed for quantifying the content of methane biogas sample. The device’s major component was a methane sensor with MQ-4. This sensor was put in airtight glass container, along temperature, humidity, and pressure sensors, interface having a programmed Arduino Uno cloned for operation and logging of data. Sensors were capable of detecting methane as low as 450 ppm within the jar but respond linearly for concentration with range from 4500 to 110,500 parts per million. A gas chromatograph fitted with thermal conduction detector was used to evaluate measurements made by the sensor to study. Examination of an absence of gas digester biogas samples used the tool produce an absolute error of 0.80 ± 0.22 per cent comparison of GC measurement. Employing 10 ml of sample size of biogas, the tool could accurately quantify methane content as small as 20 per cent per volume. Through the sample of 80 ml, content of methane could be measured small 3.4 per cent. This unit was constructed at a cost of 35- 40US dollars. A field edition with LED monitor as well as the power pack will be installed for below US$ 45-55.
