The need to protect home facilities has in recent times being a matter of great concerns to individual and government, considering the dramatic rise in crimes such as house theft, robbery kidnappings and rapes among others. Advancement in technology has enhanced the ubiquity of smart home security systems resulting in safety of lives and properties and by extension improved standard of living. The emergence of cheap and affordable microcontroller, like Arduino has enabled the design and implementation of a remote home-based security system that enhance comfort, energy saving, and convenience of home appliances. The study designs and implements a remote home security system that uses cheap hardware and software such as Arduino boards, passive infrared sensor, highly sensitive camera, GSM modem, Buzzer alarm, SD card, jumper wire and a 9v battery among others to collect information from PIR sensors, process the information and send SMS to corresponding GSM mobile phone number of the homeowner. The choice of Arduino mega was due to it affordability, user-friendly, good memory size and large number of input/output pins that guarantee accuracy and reliability. The working principle of the PIR motion sensor is based on changes in the infrared level emitted by surrounding objects when an intruder moves around a house. The microcontroller is programmed on the open-source Arduino Integrated Development Environment, which makes it easy to write code in C-like language and verifies test cases. The remote home-based security system using Ardiuno mega software is capable of integrating appliance and equipment automation with minimal energy that ensure home safety.
