India, March 2 -- The new sensor canbe used to better understand methane emissions from livestock and dairy farms; they enable a more accurate monitoring of climate crisis

An accurate detection of very low concentrations of methane (CH4) gas - a major contributor to global warming and air pollution - can be possible through a new sensor.

Measuring methane emissions and leaks was important to several industries, including the oil and gas industry, for environmental and economic reasons, according to scientists from Princeton University and the United States Naval Research Laboratory, who developed the sensor.

The findings were published in journal Optics Express February 22, 2021.

The sensor uses an inter-band cascade light emitting de...
