Solar-Powered Smart Guard: Autonomous Lighting, Intrusion Detection, and Surveillance Network

To address the increasing needs of sustainable and active security options, this research paper proposes the creation of the Solar-Powered Smart Guard which is an autonomous surveillance system that is capable of working without the electrical system. The conventional security systems tend to be affected by dependency on constant power and passive recording functions, which make them useless during downtimes or need to be monitored manually. The proposed project will overcome these shortcomings by incorporating PIR motion sensors, IoT connectivity, and a solar powered energy harvesting system into the Arduino Uno and ESP32-CAM. The system uses sensor fusion algorithms to remove noise in the environment which is a huge filter and the false alarms are minimized and the correct intrusion detection is made. After checking the movement, the device will automatically activate local deterrence by using high-intensity floodlights and audible alarms and also send real-time email alerts and photographic alerts to the user over a GSM network.
The results of the tests ensured the capability of the system to support 24/7 autonomous functioning because of its Maximum Power Point Tracking (MPPT) charging circuit and ensured a high percentage of passing the tests in the differentiation between human movement and the environmental stimuli. The Solar-Powered Smart Guard is an effective product that offers a low cost, power saving and self sustaining alternative to traditional perimeter security.
