Abstract: A plug for detecting tampering of a container is configured to close an opening of the container. The plug includes an attachment device for attaching the plug to the opening of the container, a motion sensor for sensing rotation of the plug with respect to the container, a communication device for communicating with a server, a microcontroller unit and a memory unit. The microcontroller unit is configured to compare a sensed rotation of the plug to a service schedule stored in the memory and detect the tampering of the container based on the comparison.

Abstract: A plug for detecting tampering of a container the plug being used to close an opening in a lid of the container. The plug includes an attachment for attaching the plug to the opening in the lid of the container by rotating the plug with respect to the container, a motion sensor for sensing rotation of the plug with respect to the container and a communication device for communicating with a server.

Abstract: Disclosed is a method for monitoring a fill rate of a container and communicating it, which container comprises at least a first sensor which is a fill rate sensor. The method comprises receiving an operational model from a server, comprising a predefined maximum and/or minimum value of the fill rate. The method also comprises measuring the fill rate of the container. The method further comprises comparing the measured fill rate with the operational model. The method also comprises communicating the fill rate to the server, if the fill rate is equal or above the predefined maximum fill rate and/or if the fill rate is equal or below the predefined minimum fill rate.

Abstract: Disclosed is a method for identifying location of a first container within a group of containers. Each container has an identification code and includes a sensor unit. The sensor unit includes communication means and a movement detector. The method includes at least a first sensor unit of the first container transmitting a first message including a first identification code of the first container, and at least one communication module receiving the first message. The at least one communication module analyzes the received first message, compares the received first identification code to a list of stored identification codes, updates the list of stored identification codes by addition of the first identification code when the first identification code is absent from the list, and transmits a second message to a server, the second message including the first identification code for the server to update the location of the first container.
