Development of smart LED lighting system using multi-sensor module and bluetooth low energy technology

A smart LED lighting system is designed and implemented using a multi-sensor module and Bluetooth Low Energy (LE) technology. In order to monitor the environmental information such as ambient light intensity, temperature, and/or activity of human or other objects, a multi-sensor module including an ambient light sensor, temperature sensor, and motion sensor is combined to a microcontroller. By collecting environmental information, the LED lighting system can be controlled automatically. Through the Bluetooth LE technology, a user can monitor the environmental information on a smartphone and/or control the LED lighting system manually. Two features, multi-sensor module and Bluetooth LE, let the LED lighting system be more intelligent, energy efficient, and convenient lighting system.
