Summary
GC0001-000 is the carbon dioxide sensor based on non-spectral infrared absorption principle. The principle is to radiate infrared light with constant intensity and wavelength, which is obsorbed by carbon dioxide in the air, and detect the electricalsignal of infrared light output. The sensor internally filters and amplifies the electrical signal, mcu calculates the concentration of carbon dioxide in the air through the algorithm, outputs the analog signal in PWM mode, and outputs the digital signal in the UART serial port mode.
