MH-Z19D infravörös CO2 érzékelő modul szén-dioxid gáz érzékelő CO2 monitorhoz 400-5000 ppm UART PWM kimenet terminállal
MH-Z19D Infrared CO2 Sensor Module Carbon Dioxide Gas Sensor For CO2 Monitor 400-5000Ppm UART PWM Output With Terminal
Product Details: The MH-Z19D carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor. It has : Terminal.
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.
Sensor characteristics:
High sensitivity, low power consumption
Excellent stability
Temperature compensation, excellent linear output
Provide serial port (UART), PWM waveform and other output methods
