Taidacent DC 12v Photoelectric Switch Sensor with Relay 4 Way LDR Switch Darkness Sensor Circuit Photo Resistor Sensor Module
4 way 12V photoresistor relay module with 50CM line length photoresistors. If you want to supply power to 5V, please leave a message when you take it.
4-channel 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 device. It can also be used for two kinds of sensor sensing. The triggering of two conditions is to connect the output terminal in series (AND gate). In either case, the output terminal is connected in parallel (or the door). The two groups independently control three control modes and directly connect Exchange high-power products.
1. Using a photoresistor sensor to sense the intensity of light, with its own relay, directly control the load 2. Adjust the sensitivity with the potentiometer. By adjusting the potentiometer, set the threshold of the starting relay. When the threshold is bright, the module relay is closed. When the threshold is dark, the relay is released, so it is normally open and common. The end is the switch that controls the daytime, and the normally closed and common ends are the switches that control the night. 3. Output form: load directly connected to AC 220V 10A or DC30V 10A 4, control board PCB size: 7.6cm x 6cm, small board: 7.6 X 3.6CM 5, using a wide voltage LM393 comparator
greater than 500mA
250V 10A AC or 30V 10A DC
1. The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of ambient light. 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 is 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;
1*4 channels of 12V photosensor sensor relay module, with 4 50cm long lead photosensors.
