ITEM NAME:1 pcs blue metal photodiode sensor 5V relay light control switch module 5*2 H1T9 1 pcs blue metal photodiode sensor 5V relay light control switch module 5*2 H1T9 using light-sensitive diode light intensity, comes with relays, direct control of the load with the potentiometer to adjust the sensitivity, by adjusting the potentiometer, set the threshold for starting the relay, when the light on this threshold, the module relay pull, dark below this threshold, the relay is released, so the normally open and public The end is to control the daytime switch, then the normally closed and the public end is to control the night switch. photodiode most sensitive to ambient light, generally used to detect the ambient light brightness. the module in the ambient light exceeds the set threshold, the relay pull-in, common and normally open to connect ,, when the ambient light is below the set threshold, the relay is disconnected, the common and the normally closed end connected; the public side, normally open, normally closed three ports is equivalent to a dual control switch, the relay coil has electricity, the common and normally open end of the conduction, no electricity, the public and the normally closed end of the conduction Uses: Light detection, brightness detection, through the potentiometer can adjust the detection of brightness valve, comes with relays, can do a variety of brightness detection switch, you can control a variety of street lights, turn on automatically at night, automatically extinguished during the day and car supplies control and automation equipment. (Compared with the photoresistor, the directivity is good, you can sense the light source in a fixed direction, detect the light in front of the photodiode, the periphery is difficult to detect, often should find the light function) Working voltage: 5V; Output Type: Directly connected to AC 220V 10A or DC30V 10A load, with 4 fixing bolt holes for easy installation; Small PCB size: 5cm x 2.6cm; Elec
