Device for detecting proximity of a vehicle and system for monitoring parking spaces of a parking lot

A device for detecting proximity adapted to monitor a parking space, which has relatively small dimensions, is autonomous from the energy point of view even when positioned in the middle of the parking space and does not require the provision of stations outside the parking space to be supplied by photovoltaic cells. The architecture of the device is organized in such a way as to be able to keep almost all its components turned off, which are all turned on only when there is the need to detect whether the parking space is occupied or free and only for the time strictly needed to perform this operation.
