Inspiration

Our inspiration was improving the efficiency of energy consumption of homes to help the environment, wildlife and reduce light pollution through the use of warm light.

What it does

Smart Monitoring: Ultrasonic sensors detect room occupancy
Automated Control: Arduino Uno microcontroller manages smart lighting, activating LEDs only when necessary
Warm-Tone LEDs: Produces warm-colored light that reduces light pollution, protecting wildlife and human health while being more energy-efficient
Optimized Usage: Reduces artificial light emissions by intelligently managing LEDs based on real-time conditions

This approach minimizes energy waste while maintaining comfortable living conditions.

How we built it

6 Yellow LEDs and 6 1.5K Ohm Resistors: Create warm light colors to reduce blue light exposure and minimize disruption to sleep patterns and wildlife. Resistors protect and dim LEDs to maintain energy efficiency.
Two Ultrasonic Sensors: Detect room occupancy by emitting sound waves and measuring reflection time, enabling the system to determine when someone enters or leaves a room. Each sensor controls 3 LEDs for localized lighting zones.
Arduino UNO: Central microcontroller that processes sensor data in real-time and manages LED activation based on occupancy detection.

Challenges we ran into

Our challenges were trying to setup the Arduino Uno q which did not have much documentation, and we spent a good amount of time trying to get it to work.
