IoT lab

IoT, Edge, Fog and Cloud – the HPI IoT lab offers a wide range of different types of hardware, reaching from embedded devices, over single-board computers equipped with accelerator hardware, hardened Edge devices, to Cloud hardware with high capacities. It is an inevitable resource for our research and teaching activities.
