The application of internet of things in the real world offers numerous benefits including smart homes and offices, a technology that does not only save energy but also saves money. Office automation is becoming popular due to its numerous benefits as applied in the world of internet of things. The specific objectives of the study were: to assess the current energy usage, identify current energy saving measures, and design and implement a smart energy saving system for Muni University. System requirements were collected from the respondents who were staff of Muni University. The study considered 2 respondents from estates office, 2 from procurement, 1 from each of the three departments of education, Computer and Information Science, and Nursing Sciences. User requirements were gathered a qualitative protocol using focus group discuss and thematic analysis technique was employed. Heterogeneous home automation systems and technologies were considered in review with central controller-based Arduino, sensors, web based, email, Bluetooth, mobile, SMS, ZigBee, Dual Tone Multi Frequency, and cloud based. The study design utilized the Global system for mobile communication technology as a user interface using SMS based communication with Arduino as the central controller. The system supports internet of things concept that can be applied in saving electrical energy usage in public places including public universities. The study further recommends the Ugandan government to advocate for Arduino Based Smart Energy Saving System that can reduce electrical energy expenditure in Ugandan public universities Muni University inclusive.
