20210526· mq2 센서 동작 원리. mq2 센서를 사용하여 가스를 감지하는 것은 매우 쉽다. 센서 값을 얻기 위해 디지털 핀 또는 아날로그 핀을 사용할 수 있다. 5v로 모듈에 전원을 공급하기 만하면 모듈의 전원 led가 켜지고 가스가 감지되지 않으면 출력 led가 꺼진 상태로 유지되어 디지털 출력 핀이 0v가 된다.

20171205· Which gives the Pi Analog input. For the voltage issue the plan was to use a step up converter from 3v3 to 5v for the sensor. This was my plan B. Plan A was to connect the sensor directly to the Sonoff Basic, which would be ideal as its close to the gas source to be monitored. I''m completely unsure how to enable the analog input and initial ...
