Challenge Details

Not least because of the current situation, the registration of customers and visitors in shops is important. In addition to „Covid-19 purposes“, derivations can also be made for marketing, personnel deployment, energy use and the regulation of energy technology systems such as air conditioning. In order to keep any customers‘ limits the recording must be accurate and work in real time. The data must also be fed back to the store in real time – for example via an app or a configurable „visitor traffic light“. The data should also be available external, e.g. for further real-time analysis or marketing.
The challenge is to develop a system for recording visitors in stores and to enable data transfer via LoRaWAN. In addition, the challenge can be extended to include a solution for measuring customer satisfaction and presenting the real-time data. Transfering the data via LoRaWAN creates flexibility for system deployment regardless of location.
