Function description:

This module can detect smoke concentration, and a smoke detection threshold can be set when using it. When the smoke sensor detects that the ambient smoke density is greater than the set smoke threshold, the relay closes and the alarm indicator lights up and the buzzer sounds an alarm; when the smoke sensor detects that the ambient smoke density drops below the set smoke threshold, the relay turns off At the same time, the alarm indicator will be off, and the buzzer will stop alarming.
