The purpose of this thesis was to develop an IoT device for a company called Mirka Ltd. The IoT device is designed for data collection from sanding machine and sending data to the server for later analysis. The IoT device will be located next to a sanding machine, where it will monitor communication between devices. In this case, the data collection is done without sending any data request to the sanding machine. This kind of data collection won’t disturb the sanding machine’s performance.
The sanding machine continuously produces data about the usage and conditions of the device. This data is received from built-in sensors which are located in the sanding machine’s circuit board. The IoT device is a data logger that will be attached to the Mirka’s AIROS sanding machine, which is controlled by a robot.
Thesis is divided into theoretical, practical, data analysis and future development parts. In the theoretical part the IoT architecture, communication between devices and technologies concerning the communication are discussed. After the theoretical part focus is on the IoT device itself, including the developed program, devices and tools that are used. The last part is about testing, data analysis and future development that are related to the data we collected from real use of the IoT device.
The IoT device is made using Raspberry Pi computer and 4G communication device. With the 4G device, IoT device is able to send data through the Internet to an external database, which is located in Mirka Ltd’s server.
IoT device is set up and currently running in the Mirka Ltd’s workshop in Jepua. In the future, the intention is to include it to the AIROS end product.
