PostNL has an incredible network of letterboxes on the street. Last September, we investigated the Smart City opportunities for this network by placing sensors measuring temperature, noise and humidity on the letterboxes.
I would like to receive ideas for how we can use the letterbox as install-base for sensors measuring e.g. air quality, urban heath, noise, etc.
What kind of user stories can we serve with this network of thousands of letterboxes? And what if we combine the letterbox network with our vehicles and bicycles, covering every street every day?
