Light detection, brightness detection, potentiometer can adjust the detection brightness valve point, self-contained relay, can do all kinds of brightness detection switch, can control various street lights, automatically turn on at night, automatic extinguishing during the day and on-board supplies control and automation equipment.
Module features:
1, using the photoresistor to induce the intensity of light, with its own relay, directly control the load
2. With the potentiometer to adjust the sensitivity, set the start relay threshold by adjusting the potentiometer. When it is darker than this threshold, the module relay is closed. When the threshold is illuminated, the relay is disconnected.
3, working voltage 5V
4. Output form: load directly connected to AC 220V 10A or DC30V 10A
5, with 4 fixing bolt holes for easy installation
6, small board PCB size: 5cm x 2.6cm
7, using a wide voltage LM393 comparator
2. When the ambient light exceeds the set threshold, the relay is closed, and the common end is connected to the normally open end. When the ambient light is lower than the set threshold, the relay is disconnected, and the common end is connected to the normally closed end;
3, the common end, normally open, normally closed three ports are equivalent to a dual control switch, when the relay coil is powered, the common end is open to the normally open end, when there is no electricity, the common end and the normally closed end are turned on;
Supply voltage: 5VDC
Current: greater than 100mA
Load: 250V 10A AC or 30V 10A DC
