CO2 Gas Sensor User Manual – Vernier

The Vernier CO 2 Gas Sensor measures gaseous carbon dioxide levels in the range of 0 to 10,000 ppm (Low range setting) or 0 to 100,000 ppm (High range setting) by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules. Carbon dioxide gas moves in and out of the sensor tube by diffusion through the twenty vent holes in the sensor tube. The sensor uses a …

Gas Pressure Sensor - Vernier

The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.

Simplified highly-sensitive gas pressure sensor based on ...

We propose and demonstrate a simple highly-sensitive gas pressure sensor based on harmonic Vernier effect. By fusion splicing two hollow silica capillaries, a cascaded Fabry-Perot (FP) cavity is formed. Without special photonics crystal fibers or laser machining involved, the fabrication process is greatly simplified. The interplay between the two interferometers consisting the FP cavity leads ...

A generalized approach for design of photonic gas sensors ...

· The design of photonic gas sensors based on the Vernier effect is proposed for detection of two harmful gases, , methane and ethane. Photonic sensor for methane detection in mid-IR. The design procedure starts by considering the absorption spectrum of the gas to be detected. To this purpose, methane is characterized by an absorption spectrum in mid-IR wavelength range. In Fig. 7 …
