What is a Gas Sensor? Construction, Types Working of Gas ...

20200604· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the …


Majority of US urban natural gas emissions unaccounted for ...

20211102· Methane emissions from distribution and end use of natural gas (NG) are not well known. We analyzed atmospheric methane measurements to quantify NG emissions in the Boston area over ∼8 y, finding NG emissions approximately three times larger than calculated by usagebased inventories. We observed no change in emissions over 8 y despite efforts from …
