PROJECT DESCRIPTION

The project is designed to detect obstacles by an IR sensor and to switch  the load for indicating the obstacle’s detection. This project is very helpful for  industries  to sense the movement of material on a conveyor belt.

 

The project uses 38 KHz IR signal, which is generated by feeding an IR diode received by a tuned IR receiver. These IR sensors are interfaced to a microcontroller of the 8051 family. The IR transmitter continuously transmits rays upon the receiver and when these rays are blocked by any object an interrupt is sent to the microcontroller. The microcontroller, according to the program written, performs the desired action.

A lamp is used as load in this project for demonstration purpose. This lamp is actuated by a relay which is interfaced to the microcontroller output. So when the interrupt is sent to the controller, it in turn switches ON the relay to actuate the load.

 

Furthermore, in future the project can be enhanced by using a counting arrangement with a display. This arrangement will be helpful in manufacturing industries wherein keeping a total count of production on record can be done.
