Photosensitive Resistance Sensor With Relay Module 5V Optical Control Switch Light Detection Switch

Usage Light detection brightness detection potentiometer can be adjusted to detect the brightness of the valve point with its own relay can do a variety of brightness detection switch Features 1 Using the photoresistor to induce the intensity of light with its own relay directly control the load2 Adjust the sensitivity with the potentiometer Set the start relay threshold by adjusting the potentiometer When it is brighter the module relay pulls in When the threshold is dark the relay is disconnected 3 Working voltage 5V4 Output form load directly connected to AC 220V 10A or DC30V 10A5 With 4 fixing bolt holes for easy installation6 Small board PCB size 5cm x 2 6cm7 Using a wide voltage LM393 comparator Instructions for use 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 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 Electrical parameters Supply voltage 5VDCCurrent greater than 100mAL
