1-day Study Session for Introduction to Agricultural IoT for Beginners

The study session covers everything from sensor assembly, environment setup, programming and visualisation of IoT data in five hours in the afternoon. Participants will deepen their understanding of the IoT while actually using it with their own hands. The IoT environment and kit created can be enjoyed at home after the event, allowing participants to bring home the experience.


  • The goal of this study session is to visualize the data acquired by the temperature/humidity sensor on Ambient, a cloud service, after receiving explanations about the ESP32 development board, Ambient, etc. used in the study session.
  • Practical IoT equipment (ESP32) and environment (VScode, PlatformIO) that can be easily utilized after the study session are included in the equipment set & study session program.
  • As a level, if you have used something like Word or Excel, you will enjoy this study session.


As the market size of the IT market continues to expand, a wide range of skills are needed to take advantage of new technologies. On the other hand, a problem that has arisen in recent years is the shortage of human resources with the necessary skills. In this study session, participants will experience using a small microcontroller called ESP32 to acquire/visualize data measured by sensors. We believe that the experience of operating the microcontroller with your own hands in this course will be a great first step in learning IoT.
