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.
These sensors are equipped with a high sensitive sensing element that is powered through connecting leads connected to.
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.
The sensor itself is protected by a plastic cap and a filter.
The global gas sensor market size was valued at usd 2 19 billion in 2019 and is expected to expand at a cagr of 8 3 from 2020 to 2027.
