Abstract

The routes plied are situated in Ibadan, Oyo State, Nigeria with different longitude and latitude respectively to assess the signal quality of 3G and 4G networks, compare four service/network providers in terms of coverage, service quality with respect to location, and determine areas with weak strength that needs optimization of different operators. The relevance of this study is to provide information as regards each operator in order to provide solution and to educate the subscribers for proper fixed or dynamic internet usage and voice calls. The work would benefit users within the city and the network providers. The mast is built in a sectorial way so that it could serve the arc and has a monitoring neighbor BTS (Base Transceiver Station) in sectorial way so it can circulate the area, though during the test, it was noticed that there are some areas with no monitoring neighbor BTS. The results show the received signal strength indicator (signal strength quality) of each network provider.

Abstract

This project designs and implements a solar-powered spy security system with motion detection capability. The system integrates a solar panel, charge controller, battery, PIR sensor, 555 timer IC, buzzer, WiFi module, and a spy camera. The solar panel recharges the battery, providing a sustainable power source. The PIR sensor detects motion, triggering the 555 timer IC to activate the buzzer and spy camera. The system captures images or records videos only when motion is detected, conserving energy and memory space. The spy camera connects to a smart device via WiFi, enabling remote viewing of captured footage. Testing demonstrated the system's effectiveness as a reliable and efficient security solution. This project addresses the limitations of traditional CCTV cameras, providing a more efficient and sustainable solution for home security. The design leverages principles of electrical and electronics engineering, including circuit design, electronics, and control systems. Future enhancements can include integrating Artificial Intelligence to improve security and reduce false alarms.
