Three-gas detection system with IR optical sensor based on ...

2015-11-01· In this paper, a three-gas detection system with a environmental parameter compensation method is proposed based on Non-dispersive infra-red (NDIR) technique, which can be applied to detect multi-gas (methane, carbon dioxide and carbon monoxide). In this system, an IR source and four single-channel pyroelectric sensors are integrated in the miniature optical gas chamber successfully. …

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.

How Does an Electrochemical Carbon Monoxide Sensor Work ...

Sensors in Carbon Monoxide Detectors. Electrochemical sensors use a gel to detect CO. Electrochemical sensors are mainly used to detect Oxygen and toxic gas. They measure a chemical reaction within the sensor that creates an electrical output proportional to the CO level. Essentially, EC sensors are small fuel cells composed of noble metal electrodes in an electrolyte. AlphaSense is one …

Basic Principle of NDIR Gas Detection - Heimann Sensor

NDIR Gas Measurement Principle To measure the gas concentration with precision, you need two thermopile sensors and an infrared light source. One sensor serves as reference to monitor the variation of IR source output due to source aging, power variations, etc.. The other sensor is equipped with a gas-specific narrow band optical filter.

Carbon Monoxide Sensors | CO Sensor | Alphasense

Carbon Monoxide Gas Sensors. Carbon monoxide (CO) is a particularly dangerous toxic gas, not only because it has no colour, no taste and no odour but because it is common in populated areas as a result of the burning of fossil fuels in vehicles and heating systems. Despite advances in detection, CO, or ‘the silent killer’ as it is often referred to, is still responsible for tens of ...
