Description
Internet of Things (IoT) – working in an Arduino environment. The aim of the project is to develop a complete IoT application for the collection of environmental data, using: – Temperature/humidity sensor type DHT11 or equivalent – IoT node type ESP32 with WiFi connection – LCD display, breadboard, LED, connection components – IoT platform ThingerIO (free access).

1. Job description:
The work concerns the recording of the knowledge and experiences gained by the
students from the lectures of the course. Students are asked to develop a complete IoT
application . The topic to be developed can be varied with the consent of the teacher.
Students must:
(a) research the literature on the chosen topic;
(b) to express in the work a critique of the subject.
(c) present their findings orally accompanied by observational material.
It is reminded that.
•
The work will be performed individually or in groups of up to three people. The
role of the members should be distinct (eg one responsible for the embedded
system and one for the IoT platform ).
•
The work will be submitted by the end date of the lectures.
•
The work will be presented orally accompanied by supervisory material ( slides
) during the examination of the course. During the presentation, the contribution
of each author should be clear.
•
There should be a clear reference to the sources (texts, figures, images).
•
The practical part of the work (code, implementation, measurements) will be
included in an appendix and will be presented during the examination.
•
Emphasis is placed on the overall approach and development of the subject and
especially on the students’ experiences from the course.
Students are encouraged to use any information available online, critically and always
citing the source. Writing and/or presenting the paper in English is also encouraged.
