Description
Summary:As we know, the process of transmitter and receiver is intends to be a framework for providing a comfortable usage in the communication system for human being. In the communications system, which signal or information has been transmitting and receiving waveform? But in this project, IR laser light will use in process of transmitted and received. This project show how to IR laser light detector will be used in process of receiving system. In this project we only concentrate about the receiver or IR laser light detector. The circuit used phototransistors to detect the IR laser light. When the laser light has transmitted directly to the phototransistor, the circuit automatically ON and the signal received will be amplified by audio op-amp and change it to sound. Our project has a very bright future to be a useful and high important device in either manufacturing industries or been used commercially as an automatic switch system. Finally, the objective of the report to study how to design PCB layout, understand about the operation and setting this project to an automatic switch system. In this report we also studied to consider for the system designed. Otherwise, we also have discussed and studied the component, which used in the IR laser light detector circuit diagram.
