The sensor has two ranges.
Co2 gas sensor ppt.
These sensors are equipped with a high sensitive sensing element that is powered through connecting leads connected to.
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.
Knowing this any gas sensor exposed to fresh air should match these readings.

All alarms adjustable low h2s 10 ppm high h2s 15 ppm low o2 19 5 high o2 23 5 2.
The vernier co 2 gas sensor measures gaseous carbon dioxide levels by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules.
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.
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.
The sensor can monitor co 2 as well as volatile gas concentrations using mems metal oxide sensor technology.
All alarms adjustable low h2s 10 ppm high h2s 15 ppm low co 35 ppm high co 200 ppm 2.
Carbon dioxide optical sensor concentration range 0 999 ppm typical sensitivity 30 30 ppm temperature up to 300 c response time 10 s side view of the co2 sensor.
Lon the left the pyroelectric detector with encapsulated porous silicon microcavity centered at 4257 nm on the right the ir source.
All alarms adjustable low h2s 10 ppm.
Co low 35 ppm high 200 ppm 1.
Students can use the co 2 gas sensor to measure the change in carbon dioxide levels for a variety of systems including.
Adjustable h2s low 10 ppm high 15 ppm.
Low 0 10 000 ppm and high 0 100 000 ppm.
Lel low 10 high 20.
The sensor itself is protected by a plastic cap and a filter.
In most cases single point calibration is achieved in fresh air.
