The project described in this report aims to develop a solution that integrates the qualities of a presence-based dynamic light controller, with the ones of an outdoor public light point, all in one product, providing the potential energy savings (up to 80%), while lowering installation & maintenance costs. A design concept is proposed, which consists of a casing module enclosing microwave sensors, processing units, and a ZigBee-based wireless communication module. The mentioned system allows plug & play connection with LED ballasts, independent light modules controlling with RGB control through Pulse Width Modulation (PWM), and the acquisition of varied data such as traffic information for different types of subjects, lighting conditions, energy performance, etc. Later in the process, a prototype of the system was embodied, including the elemental features proposed in the design concept; namely, motion sensing, wireless communication, tilt sensing, and intensity/color control of RGB LED modules. The prototype consists of a 3D printed casing containing electronic components such as a micro controlling unit with Zigbee, three RGB LED drivers, and the microwave sensors. The proposed solution meets the design criteria successfully, however it brings considerable challenges to be solved, such as height & angle adjustability, sensors angle adjustability, attachment to luminary, and product logic in software level. Although, during the embodiment of the prototype, a solution for many of these aspects was developed, further development is required in order to successfully implement the product in the market.
