The agrofood sector is essential in many countries worldwide for food security, food safety and nutrition but facing challenges and issues of productivity, lack of involvement from youth, climate change, and scarcity of resources. Many countries have promoted the Internet of Things (IoT) as part of the policy intervention to curb these challenges. Malaysia is not excluded. The IoT adoption in farming is being focused by the government in order to increase productivity in the industry. Currently, the IoT implementation in the agrofood sector in Malaysia is still in the early stages of development. IoT adoption by farmers, especially from micro, small and medium enterprises (MSMEs), is still far from expected. Many MSMEs may not be aware of the benefits of IoT for real-time information and reducing uncertainties in farming. Therefore, there is a huge gap in terms of reliable and timely information for decision-making processes. However, related studies on factors influencing IoT adoption among agrofood's MSMEs are minimal. Previous study on IoT in farming mainly focuses on the technical implementation of IoT. Furthermore, very few studies focus on the organization level and attitude of the owner-manager. Hence, based on the Technological-Organizational-Environmental (TOE) framework, this study will propose a conceptual framework that links the factors influencing the intention adoption of IoT in farming among MSMEs and mediating effect of attitude of the owner-manager on IoT adoption intention. This paper contributes to the existing body of knowledge and guides related stakeholders to develop suitable strategies for encouraging IoT adoption among agrofood's MSMEs.
