Heat Conduction CO2 Sensor MD62
Summary:
MD62 gas sensor consists of an active element and a reference element with the same resistance, both elements are placed in a wheatstone bridge circuit, The analyzing gas contents changes, the overall thermal coefficient of mixed gases changed correspondingly; when the active element meet the combustible gas, its resistance become smaller, when It meet other gas, Its resistance become larger(air background), the bridge circuit output the voltage change, this change increase according to gas concentration, the reference element as a benchmark while for temperature compensation.
Feature:
* Linear output signal
* Reliable performance
* Resistant to toxicosis
* Less demand of oxygen
APPLICATION
Air Quality Monitoring in Public Places
Outdoor air quality monitoring is a process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and their impact on the environment. Air pollution monitoring is to measure the types and concentrations of pollutants in the atmosphere, and observe their spatial distribution and changing rules.
