Co2 Gas Sensor Ppt

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.

Co2 gas sensor ppt.

The sensor itself is protected by a plastic cap and a filter. All alarms adjustable low h2s 10 ppm. Adjustable h2s low 10 ppm high 15 ppm. Lel low 10 high 20.

Fresh air contains approximately 78 nitrogen 20 9 oxygen 0 9 argon and 400ppm parts per million of carbon dioxide. Lon the left the pyroelectric detector with encapsulated porous silicon microcavity centered at 4257 nm on the right the ir source. Students can use the co 2 gas sensor to measure the change in carbon dioxide levels for a variety of systems including. In most cases single point calibration is achieved in fresh air.

All alarms adjustable low h2s 10 ppm high h2s 15 ppm low o2 19 5 high o2 23 5 2. A chamber containing small living things such. The sensor has two ranges. Knowing this any gas sensor exposed to fresh air should match these readings.

The vernier co 2 gas sensor measures gaseous carbon dioxide levels by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules. All other trace gases should be less than a few parts per million. Low 0 10 000 ppm and high 0 100 000 ppm. All alarms adjustable low h2s 10 ppm high h2s 15 ppm low co 35 ppm high co 200 ppm 2.

Co low 35 ppm high 200 ppm 1. O2 low 19 5 high 23 5. 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. Gas sensors are used for measuring the concentration of various gases in their vicinity such as oxygen carbon dioxide and nitrogen oxide.

The sensor can monitor co 2 as well as volatile gas concentrations using mems metal oxide sensor technology.
