Background technology
Carbon dioxide is compound common in air, is a kind of colorless and odorless gas under room temperature.Because carbon dioxide ratio
Air weight, so the concentration at low-lying place is higher.During with hand sinking or caisson, if it will cause the people in shaft bottom for improper ventilation
Member's asphyxia.The normal contents of carbon dioxide are 0.04%, when the concentration of carbon dioxide can make one up to 1% to feel unhappy, the dizzy, heart
To throb with fear, people can feel to pant, have a headache, dizziness when reaching 4%-5%, and when reach 10%, function of human body heavy clutter can be made, made
People loses one's senses, clouded in mind, breathing stops and it is dead.It can be seen that in various industrial and minerals and the environment of plant, monitoring two
It is of crucial importance to aoxidize concentration of carbon.
At present the existing carbon dioxide content monitoring device in China there are volume it is big, it is expensive, can only be in fixed location
Monitoring, monitoring mode is dumb or needs artificial hand-held the characteristics of monitoring, and causes the difficulty of large-scale promotion.
The content of the invention
The invention mainly solves the technical problem of providing a kind of high-precision carbon dioxide sensors, can realize to monitoring
