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.

PIR Motion Sensor Working! Now Debugging the BH1750 Light Sensor

Image
  I’ve been working on a project that combines a PIR motion sensor and a BH1750 light sensor to create an automatic lighting system. After troubleshooting, I successfully got the PIR motion sensor working , but I’m still working on fully configuring the BH1750 light sensor . The PIR motion sensor detects movement and adjusts the LED brightness accordingly. When motion is detected, the LED brightness increases, and when no motion is present, it dims.  My Serial Monitor confirms this, displaying messages like "Motion Detected! Increasing brightness..." and "No Motion. Dimming lights..." . This means the PIR sensor is responding correctly. However, the BH1750 light sensor is still giving me issues. The Serial Monitor keeps showing "[BH1750] Device is not configured!" , which means the sensor isn’t initializing properly.  Once the BH1750 is fully functional, my project will be able to dynamically adjust light brightness based on both motion and ambient li...

1. light intensity based on room occupancy Simulation

Image
This project is a smart lighting system that automatically adjusts light intensity based on room occupancy using a PIR motion sensor. When someone enters the room, the lights gradually brighten, and when the room is empty, the lights dim down smoothly or turn OFF. The system can also use a relay module to control high-power bulbs. I used WokWI to simulate this and also provided the code for it as well and a link of the simulation at the bottom.   Code: #define PIR_SENSOR 2  // PIR Sensor connected to Digital Pin 2 #define LED_PIN 9     // PWM LED pin #define RELAY_PIN 8   // Relay pin for full light ON/OFF   int brightness = 0;  // Initial LED brightness bool motionDetected = false;   void setup() {     pinMode(PIR_SENSOR, INPUT);     pinMode(LED_PIN, OUTPUT);     pinMode(RELAY_PIN, OUTPUT);     Serial .begin(9600); }   void loop() {     int motion = digital...
