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

ELSP
Peer-Reviewed Publication

This paper introduces a smart tracking system that helps locate building materials on construction sites more efficiently, especially in multi-storey buildings where searching manually often wastes time and money. The system uses IoT technology with barometric sensors and LoRaWAN to measure height and identify which floor materials are on. A working prototype demonstrates its potential to improve material tracking. Next steps include testing the system on real construction sites and improving aspects like energy use, data synchronisation, and signal coverage to make it practical for large projects.
