1 Channel 12V Flame Sensor Relay Module Fire Flame Detection Fire Alarm / 250V 10A AC or 30V 10A DC

Module for use:

1. The flame sensor most sensitive to sunlight is also a reaction, generally used as fire alarm and other purposes.

2.By adjusting the potentiometer, you can set the intensity of the flame sensor senses when the flame exceeds a set threshold, the relay, normally open end and connected to the public, when the flame is below the set threshold, the relay is switched off, common and normally closed terminal connected.

3.Common, normally open, normally closed three ports is equivalent to a dual-control switch, relay coil power, often beginning with common terminal conduction, no electricity, the common and normally closed terminal conduction.

4. The sensor and the flame to maintain a certain distance, so as not to damage the sensor temperature of the test flame lighters distance 80cm, the larger the flame, the greater the distance test.
