Whats de best open source methane analyzer for soil?

Groups

Dear colleagues

We study CH4 (and, CO, CO2) emissions from solid waste dumps in Brazil. We seek a low-cost and accurate sensor to make a portable biogas analyzer.  For example, the Arduino sensor MQ-4, doesn't accurate, and, is hard to calibrate them. We accept sugestions.  Thanks! Best!
