An Adruino-Based Wifi-Enabled Centralized Lighting System

Presented in this paper is centra light, one of two studies on lighting systems operated through wireless communication between Arduino and Android via Wi-Fi. Central light focuses on the development of a box-type command center equipped with an ESP8266 Wi-Fi module, which shall be in charge of communications, a 4-Channel Solid-State Relay, which shall be in charge of switching, a Dimmer Module, which shall be in charge of enabling dimming capabilities, a feedback Module, which uses ACS712 technology and will enable the system to detect malfunctions caused by loss electrical connections, and finally, an Arduino Uno, to serve as the prime mower of all aforementioned modules. Through a three-phase experimentation process, Unit, Integration, and System Test phases, central light, and twilight were developed. Unit tests were conducted to verify if the modules selected can deliver the necessary functions for the whole system to operate properly. The integration test was conducted to test the operation and behaviors of the modules when they operate together. Finally, the system tests were conducted to test the whole system and note its behaviors. As a result, a box-type device was developed that is capable of establishing communication, switching, dimming, and current detection. However, there were significant limitations that were observed in the ability of the ESP8266 to facilitate the data exchange.
