IoT-altimeter in smart pallets for material tracking on multi-storey construction sites

The efficient localisation of building materials on construction sites is a key challenge in the construction industry. Especially in multi-storey buildings, the manual search for materials leads to time losses and increased costs. This paper presents an IoT-based material tracking system based on barometric sensors and LoRaWAN communication. By utilising digital altimeters, the height of the material is determined, allowing it to be assigned to specific floors. A demonstrator was developed to analyse the feasibility. It shows the potential of the system for optimising material tracking on construction sites. Future work should focus on field tests in real construction site environments in order to evaluate its suitability for practical use. In addition, optimisations in terms of measurement synchronisation, energy efficiency and signal coverage are required to enable widespread use in complex construction projects.
