2X MH-Z19B infravörös CO2 érzékelő modul MH-Z19B szén-dioxid gázérzékelő a CO2 monitorhoz 0-5000ppm

2X MH-Z19B Infrared CO2 Sensor Module MH-Z19B Carbon Dioxide Gas Sensor For CO2 Monitor 0-5000Ppm
1. MH-Z19B carbon dioxide gas sensor uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air. It has good selectivity, no oxygen dependence and long service life.
2. Built-in temperature compensation, digital output and waveform output at the same time, easy to use.
3. High sensitivity, high resolution, low power consumption, excellent stability.
4. Provide multiple output methods such as UART and PM waveform.
5. Widely used for HVACR and indoor air quality monitoring.
