Ingy have completed a case study named Project UFOund: Improving Hospital Logistics with IoT
Here’s a snippet on Smart Lighting:
Smart Lighting and Switches
One of the challenges in mesh networking can be a large number of nodes that need to be installed and the power requirements that come along with it. However, as Sytze Terpstra from smart lighting provider Ingy explains, in the case of the UFOund project another novel idea provided a scalable solution that would not only address power requirements but would also fully support future IoT applications. Terpstra: “We have configured all the Interlight smart LED lighting fixtures as anchor nodes. These are the fixed ceiling nodes that together form the mesh network, through which the battery-powered mobile tags communicate their positions. Not only is this solution no more expensive than the normal LED lighting upgrade that
was planned anyway to save on energy costs, it also takes care of all the power restrictions. Being mains-powered the lighting provides a very low latency network which in turn enables the possibility to easily extend the amount of IoT applications that run on top of it. ”One of these applications is the integration of energy-harvesting wireless switches from EnOcean.
The beauty of these is that no power is required at all. The energy induced by pressing the button is enough to switch the light or make a ‘call’ for assistance, a bed, or whatever function you want to use it for. And, as an added bonus, the lighting offers extra functionality such as daylight compensation, smart grouping and lighting plans based on the presence or personal preferences. The presence sensor provides occupancy data which is processed and displayed in the GOOEE portal, which also catches the environmental sensor data such as air quality.
