Methane sensor module MP-4 carbon dioxide co2 module air detection program customization

1 Power supply: DC 5V (±0.01V)

2 Serial communication

3 LED3 (orange) is a working indicator, flashing for 1 minute after power-on, and then staying on constantly;

4 LED2 (red and yellow) is a carbon dioxide CO2 alarm light, which flashes red and yellow alternately 4 times after power-on, and then remains normally off. When the concentration of carbon dioxide co2 gas exceeds 100ppm, the red light of LED2 flashes and the buzzer alarms.

5 LED1 (red and yellow) is a combustible gas leakage warning light, which flashes red and yellow alternately 4 times after power-on, and then remains normally off. When the concentration of combustible gas leakage exceeds 10% LEL, the red light of LED1 flashes, and the buzzer alarms.
