In the light of the information technology revolution, the emergence of the Internet of Things (IoT) is an important development that can enhance the efficiency of daily activities, such as increasing communication efficiency for users around the world. Within this context, few users realize the benefits of using IoT services. In general, most of the previous studies focused on technical aspects of the Internet of Things, such as architectural dimensions and wireless sensor networks, and the studies did not focus on examining the perceptions of IoT users. The aim of this study is to determine the factors that affect users' adoption of IoT services in an educational institution in Iraq. Random samples were used to collect data from 302 (faculty) at Northern Technical University. The UTAUT model was used with the addition of two factors (privacy, trust), as current research confirmed the importance of these two factors in the users' decision to adopt new technologies. The current study found that social influence is the most important factor regarding behavioral intention (BI) to use IoT services followed by expected effort, privacy and performance expectations. Facilitating conditions have an impact on the behavior of using IoT services. Finally, the study recommends decision makers in higher education institutions to use Internet of Things services and work to increase users' awareness of its benefits.
