Implementation of an Object Detector Wireless Signal Transmission System

Abstract

Present Era is completely a technological age. There are so many instruments or devices are invented day by day which are used in our everyday life. Security has now become an important fact. To secure our residences, industries & bank (where higher security is required)an "object detection & wireless signal transmission" circuit is designed. Using this circuit we will be able to protect our valuable things and make our life secured & safe. The circuits consist of NE555 timer, capacitor, diode, inductor, transistor, sound chip, speaker, led, resistor, IR led, TSOP 1738, 32 KHz crystal, trimmer, 4069UB. In this project, there are four sections:  IR transmitter circuit  IR receiver circuit  Frequency transmitter circuit  RF receiver circuit The proposed design has various desirable features such as low cost, simpler control and maintenance, and good efficiency.
