We are testing whether a number of sensors in the ceiling over the queue for the school restaurant can give us data and insights on how the queue flow affects noise level, number of eating and food waste.


In the City of Helsingborg's schools, we prioritize developing meal environments that provide food. We believe that a pleasant lunch time can provide increased study peace and make more of our students choose school meals over other alternatives. We believe that long queues create stress, higher noise levels, fewer meals and increased food waste. Now we want to investigate whether this is true and explore whether we can use data from sensors to create a calmer meal environment.


The test site is Filbornaskolan - a high school where the kitchen serves almost 750 diners a day. Together with Axis, we will set up a total of 4 sensors: 3 personal counters and 1 queue length meter, which together will hopefully give a good picture of the flow in the queue and serving. The sensors measure the number of individuals / minute through blurred video streams that are instantly translated into ones and zeros. What the sensors measure will be visualized for diners via a screen, partly to tell about the test but also to tell how long the queue time is estimated to be from one moment to another.
