Abstract

The ever-evolving landscape of embedded systems and the Internet of Things (IoT) has transformed the way homes operate. The aim of this research was to develop and construct a local home automation system that replaced traditional mechanical switches with a digital touchscreen interface. The system design employed an 8-bit 8051-family microcontroller as the control logic and a 4-wire resistive touch panel for user input. For power control and safety, a 4-channel relay module was used to achieve electrical isolation between the low-level control and high-level power loads. The system exhibited almost instantaneous response, with touch-to-load delay much shorter than human response time. The addition of a 16x2 alphanumeric LCD display enabled real-time monitoring, enhancing transparency. Compared to conventional manual switches, the proposed design provided greater convenience, monitoring and safety. The results of the study found that the proposed prototype is a cost-effective, reliable and scalable solution for home automation, especially where network connectivity is not essential and reliability is a critical requirement. This study suggests future work include the addition of wireless communication and sensor networks, to develop the system into a self-monitoring smart home.
