MQ4 Methane Gas Sensor : Pinout, Interfacing with Arduino ...

The MQ4 sensor is a compact gas sensor which is highly sensitive to methane gas and less prone to alcohol and other gases. This methane gas sensor provides an output signal according to the sensed concentration of CH4 in the surrounding or environment. This sensor is proved to be effective in alarm systems, gas detection circuits whether at a ...

Infrared Point Detector for Combustible Gas Detection

Model IR400 infrared (IR) point detector is a microprocessorbased combustible gas detector that continuously monitors combustible gases in the lower explosive limit (LEL) range and provides a 4 to 20 mA analog signal proportional to the 0 to 100% LEL concentration.

Sensors | Free FullText | A Portable Device for Methane ...

Methane is a major greenhouse gas and a precursor of tropospheric ozone, and most of its sources are linked to anthropogenic activities. The sources of methane are well known and its monitoring generally involves the use of expensive gas analyzers with high operating costs. Many studies have investigated the use of lowcost gas sensors as an alternative for measuring methane concentrations ...
