This paper presents the design and implementation of a ZigBee-based automation system for engineering laboratory applications. The study employed a mixed-methods approach, consisting of system development, power consumption analysis, and a survey of 163 users. The system comprises a ZigBee network, a central processing unit, and a user interface that enables the user to remotely monitor and control laboratory equipment. The ZigBee protocol is used for wireless communication between the various devices in the network, ensuring reliable and secure data transmission. The system has been tested and evaluated in a laboratory setting, and the results demonstrate that it provides an effective and reliable solution for laboratory automation. The survey results revealed that the system was evaluated positively by the users, with an average Likert score of 4.0, indicating a high level of satisfaction in terms of operations, functionality, accuracy, efficiency, reliability, convenience, userfriendliness, and economic feasibility. . The power consumption analysis showed that the system was able to reduce energy consumption by up to 6% compared to manual switching for a one (1) hour unattended equipment and appliances. The system's main contribution is the reduction of energy wastage in the engineering laboratories, leading to potential cost savings and a decrease in the university's carbon footprint. In conclusion, the Zigbee-based automation system for engineering laboratories is a promising solution to the problem of energy wastage and offers potential benefits in terms of cost savings, environmental sustainability, and laboratory efficiency.
