Device
For the device we had to figure out what kind of data we want to gather and what components are we going to use for that. Reasoning for selected components was that they had to be recent, high quality, compatible and SMD for professional quality product. Final choices for major components were sensors: Bosch BMI055, Bosch BME280, Broadcom APDS-9960 and Bluetooth 5 module: Rigado BMD-340. PCB design was done with open source software KiCad and boards were assembled at the workshop. Protective cases were also 3D-printed at the workshop with the design being done using Blender.
