Abstract Having technology around us that can be used for household and entertainment purposes to signal any potential threat in our surroundings and trigger alerts is vital. The study designed a technology that is aimed at providing security to the environment and properties since it can detect movement at a certain angle and also give an alert. The system used a Passive infrared radiation (PIR) module HC-SR501 to detect motion and an Arduino uno microcontroller unit (MCU) to process and control the sensor data. The PIR sensors detect infrared radiation emitted by moving objects, such as human beings or animals. Several tests showed that the system performed well under different conditions, with the PIR sensor able to detect motion at different sensitivities distances, and angles. The designed prototype system reveals that our environment, properties, and even human lives can be secured, hence the technology can be deployed as a surveillance. However, the limitation could be power outages from public utilities, in terms of functionality.
