DC 5V 12V 24V MQ-2 Smoke Sensor Module Detector Switch Controller Methane Gas Biogas Alarm with Buzzer

Description:

DT-120 is a MQ-2Smoke Alarm Module.This module can detect smoke concentration.The smoke smoke threshold can be set during use.When the smoke sensor detects that the ambient smokeconcentration is greater than the set smokethreshold,the relay closes,at the same time the alarm indicator lights up and the buzzer sounds an alarm.When the smokesensor detects that the ambient smokeconcentration has fallen below the set smokethreshold,the relay turns off and the alarm indicator goes out,and the buzzer stops alarming.
