Willwin 12V Light Photoswitch Sensor Switch LDR Photoresistor Relay Module Light Detection Photosensitive Sensor Board

Module features: 1. the use of photosensitive resistance induced light intensity, comes with a relay, direct control of the load 2. with potentiometer sensitivity adjustment, by adjusting the potentiometer, set the starting relay threshold, when the dark on the threshold, module and relay, bright on the threshold, the relay is switched off. 3. working voltage 12V 4. output form: directly connected to the 220V 10A AC or 10A DC30V load 5. with 4 fixed bolt holes, easy to install 6. small size: 50mm x 26mm 7. the use of wide voltage LM393 comparator Module instructions: 1. photosensitive resistance module is the most sensitive to environmental light, generally used to detect the brightness of the surrounding environment of light. 2. module in the light more than setting a threshold, a relay, a public end and often start connected,when the outside ambient light is less than a preset threshold, relay disconnect, public ends with the normally closed terminal is connected; 3. the public side, normally open, normally closed three ports is equivalent to a double control switch, relay coil power, the public and often start conducting, without electricity, the common and often closed end conduction Electrical parameters: Power supply voltage: 12VDC Current: more than 100mA Load: 10A 250V AC or 10A 30V DC
