MH-Z19D infravörös CO2 érzékelő modul szén-dioxid gáz érzékelő CO2 monitorhoz 400-5000 ppm UART PWM kimenet tűvel
MH-Z19D Infrared CO2 Sensor Module Carbon Dioxide Gas Sensor For CO2 Monitor 400-5000Ppm UART PWM Output With Pin
The MH-Z19D carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor. It has : pin . It uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air and has good selectivity. No oxygen dependence, long life, etc.;built-in temperature compensation; also has serial port output, PWM output, easy to use.
The sensor is a high-performance sensor made by closely combining mature infrared absorption gas detection technology with precise optical circuit design and sophisticated circuit design.
High sensitivity, low power consumption
Excellent stability
Temperature compensation, excellent linear output
Provide serial port (UART), PWM waveform and other output methods
