Abstract
A long time monitoring and self-powered solar light-emitting diode (LED) lamp wireless sensor device, capable of monitoring bridge, building or structure in real-time. The device comprises a substrate, at least one LED lamp bead, a rechargeable battery, a solar cell, at least one wireless communication module, at least one sensor and a control unit. The device is contained in a casing having a transparent region and a waterproof function. The solar cell stores energy into the rechargeable battery in sunshine environment, and by comparing the sensing value with a threshold, it is determined whether a safety issue occurs, so as to emit alert. In the night, the rechargeable battery supplies power to the LED lamp beads for illumination or decoration lighting of the structure. Wireless communication links the entire system for providing safety monitoring information, LED lighting or decoration instruction.
