The project is designed to actuate a load when IR rays are interrupted by any object. his is helpful in industries for sensing movement of material in a conveyor belt for any action to be taken.
The project uses 38 KHz IR signal generated feeding an IR diode which is received by tuned IR receiver. These IR sensors are interfaced to a microcontroller of 8051. The IR transmitter continuously transmits rays over the receiver and when these rays are blocked by any object an interrupt is sent to the microcontroller. The microcontroller according to 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.
Further the project can be enhanced by using a counting arrangement with a display. This arrangement will be helpful in manufacturing industries where keeping a total count of production is required.
