Abstract:
Just like in any other city in the world street light takes play an essential role in Rwanda today with the government installing the same across the City. There is a move towards realtime street light system that can respond to the surrounding environment or actions providing a safe night time environment for all road users including foot-travelers. The Street light computerization system can reduce power consumption and maintenance costs and also supports to reduce crime activities up to certain limit. Such street light systems are mainly controlled on the basis of a combination of sensor technologies. However, most of the current systems in Kigali are based on thresholds which may lead to errors leading to increased costs and energy wastages. This thesis therefore, presents a prototype of Arduino based fuzzy logic controlled smart street lighting system so as to overcome the challenges. The study aims to implement fuzzy logic on Arduino as compared to existing solutions that depend on cloud based solutions which are a challenge implementing in Africa. The PIR sensor is used to detect motion and the surrounding environmental conditions using Light Dependent Resistors so the lighting is adjusted or switched on and off based on demand. In addition, the system will be able to monitor the working conditions of different lights and incase of any anomalies alert the concerned authorities via a GSM module. The results show that the implementation of a fuzzy inference system in Arduino did not effects its functionality an element that can be exploited to reduce on connectivity and energy costs. On implementation this system will lead to reduced costs, predictive maintenance and energy savings thus contribute towards the achievement of sustainable development goals.
