MIX8121 Semiconductor CO2 Detection Sensor for Indoor Air Purifier Air Quality Monitoring
MIX8121 Carbon Dioxide(CO2) Detection Sensor Used For Air Purifier Indoor Air Quality Monitoring
Principle Introduction:
The Carbon Dioxide(CO2) gas sensor is for air quality monitoring. It is chemical type gas sensor that adopts solid electrolyte cell principle, used to detect carbon dioxide. When sensors are exposed to CO2, battery is positive and negative electrode reaction, the CO2 sensor produces electromotive force between sensitive electrode and reference electrode, the output voltage signal can be detected carbon dioxide.
Feature:
High sensitivity to CO2
Low cost, long life
Good stability
Simple application circuit
Low power consumption
Application:
Air purifier, HAVC refrigeration
Indoor air quality monitoring
Intelligent integrated ceiling
Range hood, air conditioner
Measurement of CO2 concentration in greenhouse
