Connection Diagram of IR sensors

IR transmitter and receiver connections

In the figure the IR0, IR1, IR2, IR3 and IR4 represents the transmitter and D0, D1, D2, D3 and D4 represents the receiver.

The receiver IR is connected to the analog pins of Arduino uno or any other micro-controller.

Note: - Adjust the placing of the IR sensor after measuring the distance and place them in this order and way only. Further if you want to change the positioning then you should make slight adjustment in the code accordingly.
