12V 2 Channel Board For Arduino , More than 200mAh Current OEM

Made in China 12V 2 Channel Photosensitive Sensor Module Light Detection Relay Module

Product Details

Module for use:

• A flame sensor flame most sensitive to sunlight is also a reaction , usually used as a flame alarm purposes.
• by adjusting potentiometer , you can set the intensity of the flame sensor senses when the flame exceeds the set threshold, the relay, often beginning with a common terminal is turned ,, When the flame is below the set threshold, the relay off , common and normally Closed end turns ;
• common , normally open, normally closed three ports is equivalent to a dual-control switch, relay coil has power, often beginning with a common terminal is turned on when there is no electricity , the common terminal and normally closed terminal conduction ; ,
• the sensor and the flame to maintain a certain distance , so as not to damage the sensor temperature , the flame of a lighter test distance of 80cm, for the greater flame , the farther distance test
