LED Solar Security System

Project Description

  • The overall objective of this project is to implement an automatic solar powered LED security system designed to collect enough solar energy during the daylight to power a series of LEDs during the night. The solar collectors will gather a sufficient amount of power to make the LEDs shine at a minimum brightness. Motion sensors will also be implemented into the system to detect movement and brighten the LEDs also sending a message notifying a security director of some sort. The solar panels will use power to charge a battery or series of batteries during the day and the LEDs will draw power from that source at night. If an LED goes out or does not have enough energy to illuminate, the system will be designed to gather energy from one of the other sources. Also, if there is any type of power failure, a message will be sent again to an outside source for help. Applications for a project like this are mainly large scale. We would see systems like this outside of buildings, spotlights that tell when there is movement in an area, whether it be an intruder or not. Clients would expect a product like this possibly as a model before the design of a building by using a small scale rendition to show what the large scale will be able to accomplish.
