Abstract
A beacon device includes an antenna, a low-power RF (Radio Frequency) device, a light sensor, a microprocessor, and a battery. The low-power RF device generates an RF signal, and the antenna transmits the RF signal outwardly. The light sensor detects intensity of light nearby, and generates a detection signal. The microprocessor controls an operation mode of the low-power RF device according to the detection signal. The battery supplies electric power to the low-power RF device, the light sensor, and the microprocessor.
