January 25, 2021 Wilsen Sensor Level sensors in LoRaWAN technology optimise the logistics of circulating containers that transport raw materials between manufacturers and consumers. The low-power wide-area technology used saves energy and enables users to operate a private wireless network on-site. There is not a logistics manager who has not always dreamed of containers that independently report when they need to be refilled. Autonomous level sensors and new wireless technologies that can be operated privately on a company’s premises now finally fulfill this wish. Mobile Containers Report Independently In the Internet of Things, objects that did not have their own voice before get a chance to “speak.” Today, battery-powered sensors can capture vital data about the location and current fill level of mobile containers, tanks, and silo containers and provide the supply logistics chain with this information. One example of this is mobile silos that transport plastic granules from the manufacturer to the processing injection molding company. At the injection molding site, the granulate is gradually removed and the empty container is sent back to the granulate manufacturer. In such a circulation system, hourly information about the location and fill level of the silo is especially valuable because it can prevent the supply chain from being broken in the case of doubt.
