Abstract
A device is provided for detecting an automobile. The device includes a body, an energy harvesting portion, a sensing portion, a processing portion and a communication portion. The energy harvesting portion can harvest energy from a source external to the body. The sensing portion can output a signal and has a low-energy detector and a high-energy detector. The low-energy detector can detect a first parameter using a first level of energy. The high-energy detector can detect a second parameter using a second level of energy, wherein the first level of energy is lower than the second level of energy, and wherein the signal is based on the second parameter. The processing portion can output a signature based on the signal. The communication portion can wirelessly transmit an output signal based on the signature. The energy harvesting portion can supply energy to each of the sensing portion, the processing portion and the communication portion.
