Winterswijk – Nobody will have noticed it but the bins in the center do not only look artistic because of their “Mondriaan appearance”; they also prove to be smart. The waste bin reports to be emptied. This saves costs in logistics and also precents unnecessary CO2 emissions. It is a practical example of Internet of Things (IoT) & smart city, of which more and more applications are being put into practice. The only brake on development could be the Privacy Act: this does not bother the waste bin.
Three companies have found each other on the initiative of the municipality: Grijsen, producer of street furniture, supplies the waste bin. Teneo IoT, developer of smart sensor applications, and Hibernis, a software development company. Hibernis developed, among other things, an app for the Volksfeest Commision and is known under the label “Carepoint” in health care. In the newly established IoT Café, Inou Heideman, co-owner of Teneo IoT and Chris Krabben, director of Hibernis and Carepoint, gave a presentation about the many innovative options that IoT and Smart City offers based on the smart waste bin from Grijsen.
How does it work?
Heideman: “There are products that contain data that you can do something with. In the case of the waste bin you may ask yourself: should the waste bin already be emptied? Was it emptied on time? Is the waste bin too large or too small and is the waste thrown in the bin? It would be a shame if the bin was emptied while there was almost no waste in it!”
How do you get this information to people without always sending someone along?
Heideman: “We use LoRa(WAN).” This is a communication technique just like for example Wi-Fi, but with the advantage that it is much cheaper and can achieve longer distances. No subscription is required and it uses very little power. It works on two AA batteries, which last 5-10 years, or the system can be powered by a solar cell. The sensor measures the height of the waste in the bin and the data is sent via “LoRa”.”
Chris Krabben who –as he says- deals with the zeros and ones-shows on the basis of examples that all sorts of further applications are possible with the transmitted data.
“We convert Big Data into Smart Data.” The next step is the automatic pressing of the waste if necessary. Krabben: “You can link collection routes to it, the waste bin can schedule itself in the route.”
Other applications are the pantry, which indicates which products must be supplemented via sensors. There is also the possibility that the pantry carries out the new order itself. The smart planter regulates its own irrigation via the moisture measurement and even takes the weather forecast into account via “rain radar.”
The legionella bacteria can be controlled by monitoring the flow and temperature of the water. The system can then indicate that the tap must run for a while to prevent legionella contamination. Technically speaking, the possibilities are endless: from indicating free parking spaces to a reminder that you have to take your pills or start exercising.
