The academic article shows the use of the CDIO (Conceive, Design, Implement and Operate) methodology to develop a heart rate meter as an electronic product of the Internet of Things. Due to the outdated curriculum of the Electronic Engineering program of the Surcolombiana University, the lack of knowledge in electronic design issues with prototyping of circuits applied to IoT solutions and the lack of a clear reference methodology for the development of this type of products, it is considered necessary to know, propose and apply the stages of the CDIO initiative. This will allow sixth-semester students, who enroll in the course "Cloud Applications with Embedded Systems" belonging to the new curricular plan, and who will be the future Electronic Engineers of the Huila region, to acquire the technical and soft skills and competencies necessary to develop IoT products and solutions that are robust, scalable, secure, and tailor-made. With the design and use of a web application as an intuitive technological tool in the conception stage, it is easier to diagnose the context of the application, select devices and IoT platforms, determine technical characteristics and analyze costs based on the sizing of the IoT solution.
