A SMART MICROCONTROLLER BASED AUTOMATED VOICE REMINDER AGAINST ITEMS MISPLACEMENT IN A PUBLIC TRANSPORT

Abstract

Hypoxia is a condition characterized by a deficiency of oxygen in the body or a specific organ or tissue, leading to Misplacing invaluable items like phones, wallets, office keys, etc in a public transport is a hurting experience. Most times, passengers misplace or forget their precious items while alighting from a bus. In most cases, other passengers would pick those items and go away with them. Most times the drivers of such vehicles no nothing about the incident but gets to know after the act is over. This is very hurting and most time not easy to bear the loss. Currently in our public transports in Ebonyi State, there is no system installed in a public transport that reminds the passengers to ensure they pick up their items before leaving the bus. Therefore, this work proposes a smart microcontroller based automated voice reminder against mobile phone misplacement in a bus. The system is made up of a touch sensor which is mounted next to each passenger. The passenger will place his hand on the touch sensor once he is seated. As long as he places his hand on that sensor, the microcontroller receives signal to maintain the off state of the voice module. But once the passenger wants to leave the bus and eventually removes his hand from the sensor, the microcontroller receives the signal to turn on the voice module to play a recorded voice. By this, the passenger is reminded to pick up his items. Object Oriented Programming (OOP) method has been adopted in the implementation of this system as it ensures post-maintenance easiness.
