Towards Smart Cities: A Low-Cost Battery Operating Electronic System for Vehicles Smart Parking

摘要

A simplified electronic solution is here presented for the realization of a smart-parking low-cost system. The proposed solution is based on a commercial microcontroller-based Bluetooth low emission (BLE) board and a magnetic sensor operating in a long-time duration battery configuration architecture. The proposed system is able to detect and find the occupied parked location and communicating the result with a BLE device such as a smartphone by means of a dedicated algorithm. The vehicle detection is obtained by means of a magnetic sensor working accurately in outdoor conditions. Thanks to a very low power consumption sleep mode and the BLE wireless connectivity the sensor node can work for two years with a commercial 3V 2200mA battery.
