Functional description
This module can detect smoke concentration, and a smoke detection threshold can be set during use. When the smoke sensor detects that the ambient smoke concentration is greater than the set smoke threshold, the relay closes and at the same time the alarm indicator lights up and the buzzer sounds an alarm prompt; when the smoke sensor detects that the ambient smoke concentration drops below the set smoke threshold, the relay turns off. At the same time, the alarm indicator light is off and the buzzer stops alarming.
