Adobe Stock What do an IoT gateway and a wind farm in the Netherlands have in common? More than you might think. A 27-megawatt wind farm supplies clean energy to more than 27,000 households in the Port of Moerdijk area. The 120-meter-high wind turbines were built by Nordex and are operated by Vattenfall, a European green energy company. In addition to generating clean energy, the local officials realized the turbine towers could also serve as a great location to host an IoT network that provides key sensor data to the busy port 120 meters below. The Kerlink Wirnet iStations are piggyback on wind turbines, receiving sensor data and information and securely transferring it to users via the IoT network. In addition to monitoring air quality, including CO2 emissions, sensors installed across the area are used for monitoring water levels and open or closed bridges and gates, which helps traffic move efficiently and reduces vehicle emissions.
