The H900 air quality detector is a desktop air quality detector with a built-in high-quality air quality sensor module. It can display real-time parameters such as CO2, temperature, and humidity in the air on a LCD screen, and can also be equipped with WIFI communication
Infrared version of carbon dioxide detector: The infrared carbon dioxide gas sensor utilizes the absorption of characteristic infrared wavelengths by carbon dioxide gas, which conforms to Lambert Beer's law. The basic principle is that an infrared light source emits an infrared beam through the sampling chamber, and uses the carbon dioxide gas component to absorb specific frequencies of infrared radiation. Compare with electrochemistry, catalytic combustion, solid electrolytes, semiconductors, and photoacoustic methods.
The NDIR detection method has the following advantages: good selectivity, less susceptible to toxic aging caused by harmful gases, fast response speed and good stability, and high signal-to-noise ratio for accurate detection
CO2 indicator: 0~999ppm, green flashing；
1000~1999ppm, yellow flashing；
2000~2999ppm, orange flashing；
3000~3999 ppm, red flashing；
3999 ppm~5000ppm or above, all four colors flash
Every time CO2 air quality monitor reaches 1000ppm and above, the buzzer will beep for 1s as a reminder, only once.
