The MQ-2 smoke delay module requires a supply voltage of One2V

Product features:

With 1 MCU control, other functions can be customized;
2 to provide a variety of power input connection, to meet a variety of different needs;
3 with anti - power supply connected to anti - protection diodes, effective protection of products;
4 with a high current voltage regulator, to provide adequate power supply;

5, the use of high performance timing CPU design, double PCB board;

6, there is a power indicator (red LED) and switch trigger timing instructions (green LED);

7, the output can be connected to AC 10A 30V or DC 10A 250V load;

9, this module forsmoketouchWhen the hair.smokeAt a certain concentrationtime(the green LED light sensor moduleA),Instant start timing module is closed., green LED light time delay relay, relay, time end, green LED, release relay returned to normally closed end.(such as a direct trigger endSmoke signalLED (green lightA)The relay is always connected,Smoke signal(green LEDOut)After disconnection, start time, delay time to relay off);

11, such as when the triggering end time, continue to receivesmokeThis module will always delay signal, down relay does not disconnect and flash, until the stop trigger, will stop the clock;

12, timing potentiometer adjustment time,The product design for 1-180 seconds adjustable, can also be customized time range;

13, the time error of 5%

Product application:

1, with other kinds of sensors and relay module, can do all kinds of delay switch, directly with AC 220V products;

2, then methane / gas / combustible gas sensor can do all kinds of alarm delay trigger.
