Design and Implementation of an ESP32 Based Dual – Channel Intelligent Bracket – Lighting Controller
Subject area: Science,Engineering and Technology · Area of research: Hardware Design and Machine Learning
Abstract
This paper presents the design and implementation of a compact embedded controller for two independently operated bracket-lighting loads. The prototype combines an ESP32 microcontroller, an isolated relay-output stage, ambient-light and passive-infrared sensing, temperature and humidity monitoring, local push-button control, a liquid-crystal display, audible feedback, and an IEEE 802.11 wireless local area network interface. A modular hardware architecture separates mains conversion and load switching from the extra-low-voltage sensing and logic domain. The implemented unit supports independent or simultaneous switching, local override, sensor-assisted automation, and browser-based control on the local network. Functional integration tests confirmed stable low-voltage operation, correct sensor response, dependable relay actuation, and restoration of network communication after interruption. The principal contribution is a low-cost, explainable, and locally operable architecture that preserves essential lighting functions when Internet access is unavailable. The study also identifies the need for quantified energy, latency, electromagnetic-compatibility, and endurance testing before product deployment.
