·        Infrared (IR sensor)

·        5v single channel relay module

·        5v power supply

·        Jumper wires

·        First, connect all pins of IR sensor with jumper wires.

·        Now connect the VCC pin of the IR sensor with the positive wire of power supply.

·        Then connect GND to negative of the power supply.

·        Now do the same with the relay.
