Internet of Things
The Internet of Things (IoT) is developing dramatically, providing important information, remotely managing different technologies and gradually making our daily lives easier. This development is mainly due to modern electronics and wireless data low power transmission technology. This ensures that a conventional IoT device is in operation with one battery for several years. Examples of applications include accurate shipment tracking, remotely controlled device switching, water status and water meter control or complete irrigation control. For the Internet of Things, nvias also wants to educate new creators, so we have prepared an IoT workshop in cooperation with TData in the designated areas – SIT Port Garage. The workshop was free of charge for students and was fully funded by the Information Technology Administration of Pilsen.
Production of an IoT sensor
The students produced their own battery-powered LoRa sensors based on Microchip, Murata, Bosch Sensortec and others. Indeed there were no toys. IoT Workshop really surprised us. Although it was targeted mainly for participants with no previous electronics manufacturing experience, they all did their job.
The workshop lasted for 3 days and during this time students were asked to install professional hardware and then apply the firmware they customized. The first day was a fundamental theory that the students appreciated later in the implementation and programming of their sensors. For example, they learned what equipment and tools they will have and how to use them. They also learned about the design process and the scheme of their new IoT sensor.
On the second day, they were already preparing components and putting on PCB (printed circuit board). In the evening, they even started testing, removing bugs, and fine-tuning details.
Finally, on day 3, they started firmware programming their created sensors and sending data through the LoRa network to the cloud, where they created their own data visualization. At the end, everyone took home their manufactured IoT sensor, which measures temperature and humidity. Everyone then chose how sensor will be used. One of the teams might have placed it in SIT Port Garage to monitor their work environment.
According to the feedback from the participants, there is a huge interest in PCB design, firmware programming and the development of the application itself. So we are still preparing for you. We’re sure you have something to look forward to! And we thank to TData s.r.o., nvias.org a Sprava informacnich technologii mesta Plzne p.o.
