    4.5 mm LDR – Light Dependent Resistor

     Original price was: ₹10.00.Current price is: ₹6.00.
    • LDR(Light Dependent Resistor) also known as photoresistor is a resistor whose resistance varies with the amount of light falling on it. This is a large size LDR with a size of 4.5 mm.
    • To use, connect one side of the photo cell (either one, its symmetric) to power (for example 5V) and the other side to your microcontroller’s analog input pin. Then connect a 10K pull-down resistor from that analog pin to ground. The voltage on the pin will be 2.5V or higher when its light out and near ground when its dark.
    • This sensor can be used for making a light sensor, colour sensor, object sensor, line sensor, etc.
