5V/12V Photoresist Sensor Plus Relay Light Control Switch Module Llight Seeking Light Detection SwitchItem NO.: SUNLEPHANT0003

5V/12V Photoresistor Sensor

Electrical Parameters:

● Power supply voltage: 5VDC, 12VDC

● Current: more than 100mA

● Load: 250V 10A AC or 30V 10A DC

● PCB size: 5 * 2.6cm

Purpose:

Light detection, brightness detection, through the potentiometer can adjust the detection brightness valve point, with its own relay, can be used as a variety of brightness detection switches.

Module Features:

1. The photosensitive resistor is used to sense the intensity of the light, and the built-in relay is used to directly control the load

2. It is equipped with a potentiometer to adjust the sensitivity. By adjusting the potentiometer, the threshold value of the starting relay is set. When it is on, the module relay is closed, and when it is dark, the relay is disconnected.

3. Working voltage 5VDC, 12VDC

4. Output mode: directly connected to AC 220V 10A or DC30V 10A load

5. There are 4 fixing bolt holes for easy installation

6. Small PCB size: 5cm x 2.6cm

7. Use wide voltage LM393 comparator

Module Instructions:

1. The photoresistor module is the most sensitive to the ambient light, and is generally used to detect the brightness of the ambient light.

2. When the ambient light of the module exceeds the set threshold, the relay is closed and the common end and the normally closed end are connected. When the ambient light of the module is lower than the set threshold, the relay is disconnected and the common end and the normally closed end are connected;

3. The three ports of common end, normally open and normally closed are equivalent to a double-control switch. When the relay coil is powered on, the common end and normally open end are connected, and when there is no power, the common end and normally closed end are connected;
