Abstract
This project presents a Solar-Powered Cell Phone Detector—an innovative and eco-friendly system designed to detect active mobile phones using renewable energy. The primary goal is to offer a sustainable, off-grid solution for environments where mobile phone usage must be restricted, such as examination halls, confidential meeting rooms, and high-security zones. Traditional detectors typically rely on conventional power sources, making them less practical during outages or in remote areas. This system addresses such limitations by incorporating solar power, ensuring continuous operation and aligning with green technology goals. The system comprises a 12V solar panel that charges a 3.7V lithium-ion battery through a regulated charging circuit. The battery serves as the primary power source for the RF detection module. At its core is a high-gain RF detector circuit capable of identifying radio frequency (RF) signals emitted by mobile phones during activities such as calling, messaging, or internet use. An NPN transistor functions as a switch that activates a buzzer and LED when an RF signal is detected. Testing and calibration demonstrate successful detection within a limited range of a few meters. Although minor interference from nearby wireless devices was observed, the system offers promising performance in enclosed settings. This project highlights the potential of renewable-powered sensing technologies for modern surveillance applications and underscores the feasibility of sustainable mobile detection systems
Keywords: Solar-powered device, RF detection, mobile phone surveillance, renewable energy system, wireless signal monitoring
