Currently companies are facing the need to improve the efficiency of logistics processes by providing up-to-date information about storage and transport conditions to their customers. This necessitates the use of the Internet of Things (IoT) as well as processing and analysing large data sets. The authors asked themselves about the effects of implementation of IoT sensors which was the reason for taking up this topic. The authors put forward a hypothesis: The use of IoT sensors can positively affect the work and reduce costs in the company. To verify this hypothesis two objectives have been adopted. The first, of a theoretical nature, consists in setting out the definitional framework and possibilities of using the IoT in supply chain management. The second, of a practical nature, concerns the presentation of the implementation of the IoT and determining the potential effects and benefits for Raben Group. One of the most important achievements of this article is a literature review on the effects of IoT implementation. The implementation of IoT technology in Raben Group has allowed for achieving business results such as: increasing data quality, freeing employees from monotonous work, increasing system redundancy, increasing supply chain transparency and reducing costs. The article is an original approach to the effects of implementation of IoT sensors by indicating ones which are the most common in the literature as well as those observed by Raben Group.
