Design of a Microcontroller Based Community Security System for Developing Nations
Journal of Engineering Research and Reports,
There can never be any time in the history of mankind that issue of community security secures the rapt attentions of all and sundries. It is believed in many security circles that the upsurge may not be unconnected from craves for materialism, ubiquitous social media technologies and a breakdown in citizen’s value systems. The design uses an AtMega328P based Microcontroller to develop the security system. It uses Photosensitive and Passive Infrared devices as sensors. Codes were written and compiled. Simulation was done using Proteus while implementation was achieved on breadboard. The system operates each time an intruder is sensed; with the presence of any burglar, a buzzer sounds an alarm and security lighting system switch on for five minutes. A 16 by 2 LCD unit displays the state of the machine. It is believed undoubtedly that the loud noise from the buzzer will keep awake the domestic buildings’ occupants and other security conscious neighbours thereby scaring away the unwanted guests.
