Sensors | Free Full-Text | A Low-Cost NDIR-Based N2O Gas ...

This research presents a low-cost, easy-to-assemble nondispersive infrared (NDIR) device for monitoring N2O gas concentration in agricultural soils during field and laboratory experiments. The study aimed to develop a cost-effective instrument with a simple optic structure suitable for detecting a wide range of soil N2O gas concentrations with a submerged silicone diffusion cell.

Optical sensor for the detection of nitrous oxide - SOPRA ...

· Nitrous oxide (N2O) is a greenhouse gas (GHG) characterized by a Global Warming Potential 298 times higher than CO2. It is therefore mandatory to measure the gas flows at the soil/air interface in order to evaluate the environmental impact of the emissions coming from agricultural productions. These measurements allow direct actions to be taken in order to reduce these

The sensors waterproof eloxated aluminium casing can either hang directly in the water which allows it to move freely with the current flow or it can be fixed in position – se examples below. The sensor has a build-in temperature sensor for post-normalization of data. The sensors glass tip is kept clean by the friction forces created by the water flow. The signal from the sensor is ...

Metal oxide semiconductor N2O sensor for medical use ...

In order to develop a semiconductor type gas sensor applicable to the monitoring of N 2 O in air, a search for the semiconducting oxides sensitive to N 2 O was carried out. Among the 23 kinds of single oxides tested, SnO 2 turned out to give the highest sensitivity to N 2 O, although the sensitivity was not high enough. The N 2 O sensitivity was found to be promoted effectively when SnO 2 was ...
