Background Research

 Why is Smart Lighting Important?

  • Lighting accounts for 15-20% of global electricity use.
  • Energy-efficient lighting can reduce power consumption and environmental impact.
  • Traditional lighting wastes energy when left on unnecessarily.

How Smart Lighting Solves These Problems

  • Automated control: Lights turn ON/OFF based on occupancy (PIR sensors).
  • Ambient light sensing: Adjusts brightness depending on natural light levels.
  • Gesture control: Offers a touch-free and convenient way to control lighting.
  • Remote access: Wi-Fi module enables mobile/web control.

Energy Savings with Automated Lighting

  • Research by Smith et al. (2023) found that smart lighting systems can reduce energy consumption by 40%.
  • Studies highlight that motion-based control significantly improves efficiency.

Gesture-Based Smart Lighting Control

  • Doe (2021) analysed how computer vision-based gesture control improves user experience.
  • Results showed that gesture-based systems had 85-95% recognition accuracy.

Integration of Sensors and IoT

  • Jones & Patel (2022) showed that combining PIR motion sensors + light sensors + IoT creates fully adaptive lighting systems.
  • These systems improved user comfort while minimizing unnecessary lighting usage.

challenges I may face when doing the project

Accuracy of Gesture Recognition – Camera-based control may struggle in low light conditions.
Response Time – System must process data quickly to avoid delays.
Hardware Limitations – Raspberry Pi 5 is powerful but may need optimized algorithms for efficiency.
User Adaptability – Some users may prefer manual controls over gestures.
