Abstract: A mesh network includes an array of stationary sensing devices. Each of the devices is controlled by a microprocessor control unit and has a sensor capable of detecting a non-stationary object that enters a detection range of the sensor. A wireless communication component allows the sensing devices to wirelessly communicate with any other sensing devices or mobile phones within communication range. The devices include a power harvesting component that collects energy from the environment and a power capacitor that stores the collected energy. The devices automatically communicate data concerning any detected non-stationary objects to a central server.
