A container (e.g., a garbage bin or document disposal bin) includes a sensor for sensing a quantity indicative of the amount of items deposited into the container, and a local controller capable of wireless communication with a remote controller for sending the sensed data to the remote controller. The sensor may be mounted on the cover or at the bottom of the container. The sensor placed on the cover may be a range finder that measures the distance between the container and its content. The sensor that is placed at the bottom of the container may be sensitive to the weight of the container and its contents. The sensor may be, for example, a reflective IR range finder, or a pressure sensor, such as a force sensing resistor. In addition, the sensed quantity may be the presence of a gaseous compound, such as hydrogen sulfide, ammonia and methane. |
