Modern mems based volatile gas sensors require less power and are small enough and low power enough to use in remote locations as part of a vast network of sensors.
Gas sensors are used for measuring the concentration of various gases in their vicinity such as oxygen carbon dioxide and nitrogen oxide.
The sensor has two ranges.
All other trace gases should be less than a few parts per million.
Fresh air contains approximately 78 nitrogen 20 9 oxygen 0 9 argon and 400ppm parts per million of carbon dioxide.

Knowing this any gas sensor exposed to fresh air should match these readings.
The sensor can monitor co 2 as well as volatile gas concentrations using mems metal oxide sensor technology.

Students can use the co 2 gas sensor to measure the change in carbon dioxide levels for a variety of systems including.
These sensors are equipped with a high sensitive sensing element that is powered through connecting leads connected to.
The sensor itself is protected by a plastic cap and a filter.
