Function Description Ground potential UART Mode：Serial port transmit output PWM Mode：No connection Supply voltage UART Mode：Serial port transmit output PWM Mode：PWM Mode Select： =0 UART Mode =1 PWM Mode Cautions: 1. The sensor must be installed vertically to ensure that the gas path is smooth and avoid contact with organic solvent. 2. To ensure smooth detection of gas flow outside the air flow can smoothly into the sensor optical cavity and timely discharge. When applied to the air refresher, the fan inlet and outlet air flow can not affect the stability of the sensor detection gas path,...
