Wireless sensor network for exhausted oil collection management

Sensor networks have a large diffusion in several areas, using different kind of sensors, different line for data transmission and different ways for their collection and management. In this paper we present a particular typology of sensor network, created for optimally manage the collection of exhausted oil stored in particular bins located in a wide area (about 20.000 km²). A sensor is located on each bin measuring the distance from the lid of the collected oil; a transmission module communicate, once a day, the oil and the battery level to a web server via GPRS. In this way the control center (on a web server) has a complete overview of the situation in a wide zone, in way to optimize the run of collectors only in points that require an operation.
