Open path line of sight IR gas detectors work by emitting a beam of infrared light across an area, and then measuring the amount of light that is absorbed by gases in the path of the beam. When a gas is present in the path, it absorbs some of the infrared light, causing a decrease in the intensity of the beam. This decrease is detected by the sensor, which triggers an alarm to indicate the presence of the gas.
