Modeling of Digital Scale Based on IoT

This system is designed to be able to measure the weight of an item and record IoT-based measurement results by displaying it through a database on a website automatically. Because the livestock sector in Indonesia is still largely unorganized and there is a need for clear supply chain management and support for supply chain performance, even though supply chain management has been made, stock taking still needs to be done. and can result in an imbalance with the number of items in the warehouse and also inefficiency for the company if it wants to see stock. Therefore, the author developed a digital weighing system using 4 IoT-based load cell sensors by recording measurement results through a database and displaying them in real-time on the LCD (Liquid Crystal Digital) and website. The development method used in this research is the prototype method, namely by realizing the system design that has been made. The conclusion of this study is the realization of a digital scale model using four IoT-based load cell sensors, with an instrument accuracy rate of 99.94373%, and the test object is large with a weight of 2-11 Kg.
