KNACRO SRD-12VDC-SL-A DC 12V Relay Module Photodiode 2 Channel Module Combined Photosensitive Sensor Module Light Detection

1. Author after sensor to sense the intensity of light, with a relay, direct control of the load 2. by the potentiometer to adjust the sensitivity, by adjusting the potentiometer, set the start sensor threshold, when the sensor senses the light brightness is greater than this threshold Threshold, the relay release, the relay switch is disconnected 3, the working voltage 12V. 4, the output form: AC 220V 10A or DC30V 10A load. 5, with four fixed bolt holes, easy to install. 6, small board PCB size: 5cm x 2.6cm. 7, using a wide voltage LM393 comparator. Electrical parameters: Supply voltage: 12VDC; Working current: 76mA; Load: 250V 10A AC or 30V 10A DC; Module instructions: 1, photosensitive resistor module is most sensitive to ambient light, generally used to detect the brightness of the ambient light. 2, the module in the ambient light exceeds the set threshold, the relay pull, relay switch connected, when the ambient light below the set threshold, the relay is off, the relay switch off. Package Included: 1*DC12V 2-Channel Photoresistor Sensor Relay Module
