CO gassensing at low temperature using CuO thin films ...

Carbon monoxide (CO) is known as a silent killer, as breathing in CO gas ambient for long periods with a concentration above the tolerance limit can cause severe health hazards and even death. CO concentration as low as 30 ppm (parts per million) inhaling for few hours can significantly affects the human health. This work focuses on CO gas sensing behaviors of cupric oxide (CuO) nanostructures ...


Understanding a Gas Sensor | Jaycon Systems

20160509· In this case, the MQ4 gas sensor can measure Liquefied Petroleum Gas (LPG), Methane (CH4), Hydrogen (H2), Carbon Monoxide (CO), alcohol, and smoke concentrations. The sensor has a built in variable resistor that changes its value according to the concentration of gas. If the concentration is high, the resistance decreases. If the concentration is low, the resistance increases. Besides the ...

Everything You Wanted to Know About Multigas Detectors!

CO + H2O > CO2 + 2H+ + 2e. The metal oxide semiconductor (MOS) sensor can be used to detect both toxic and combustible gases. It operates using a heated metal oxide semiconductor. The gas molecules adsorb onto the heated surface where an oxidationreduction reaction occurs causing a change in the electrical conductivity of the metal oxide. This change is proportional to the concentration of ...
