2. Introduction
The auto brightness lamp is a smart lighting solution that automatically
adjusts its illumination based on the ambient light conditions in your
surroundings.
This innovative lamp ensures your space is always perfectly lit, providing
both convenience and energy efficiency
This helps to reduce energy consumption during the day and minimizes
glare at night, thereby improving safety and sustainability.
3. Problem Statement
• As per the AHO (Automatic Headlamp On) rule enforced from April
2017, two-wheeler headlights must remain ON at all times to
enhance road safety.
• Constant headlight brightness leads to unnecessary battery power
consumption, especially during well-lit areas or during mornings
headlights are often not required.
• At night, excessive brightness can cause glare, potentially disturbing
other drivers and increasing the risk of accidents.
4. Objectives
• The objective of this project is to develop a Smart Lighting System
for Vehicles that automatically adjusts the brightness of the headlights
based on surrounding ambient light conditions.
• This system aims to Enhance road Safety, Reduce Energy
Consumption, and Improve Driving Comfort by optimizing light
intensity according to real-time environmental changes.

7. Proposed System
• Auto Brightness Lamp for Vehicle.
• The Auto Brightness Lamp automatically adjusts headlamp brightness
based on surrounding light using an LDR sensor and ESP32
microcontroller. It also allows users to control brightness remotely via
the Website, providing better visibility and energy efficiency.
• Advantages:
Better Safety, Energy Saving, Remote Control, Supports AHO
Rule, Eco-Friendly
9. System Modules
Module 1 : Sensor Data Collection Module
Gathers real-time light intensity data using an LDR sensor to
detect surrounding brightness conditions.
Module 2 : Control Logic & Decision Module
Processes the sensor input and decides whether to turn the LED
ON or OFF, or adjust brightness, based on predefined
thresholds or user settings.
Module 3 : Simulation & Validation Module
Simulates circuit behavior using software tools to validate
sensor readings, control logic, and relay actions before physical
implementation.
10. System Modules
Module 4 : Hardware Integration Module
Integrates all components — LDR sensor, ESP32, Relay module, and
LED — into a working circuit and ensures real-time interaction with the
environment.
Module 5 : Wi-Fi Communication & Manual Override Module
Enables remote access via WiFi for the user to manually override or
customize brightness settings through a web or mobile interface.
Module 6 : Deployment & Testing Module
Installs the system onto the vehicle and tests in real-world conditions
like day, night, tunnels, and varying speeds to ensure reliable performance.
11. Methodology / Technology Used
Technologies & Tools Used:
Micro Python, ESP32, LDR Sensor, HTML, CSS, JS, Wi-Fi module
(inbuilt in ESP32), ADC and PWM modules.
Methodology Followed:
SDLC (Software Development Life Cycle) – Waterfall Model – step
by step development : Requirement, Design, Implementation, Testing,
Deployment.
Frameworks / Platforms:
Thonny IDE, Local Web Server (ESP32), Socket Programming.
12. Implementation
• Start the System
Power on ESP32 and initialize LDR, LED, and Wi-Fi. Start the web
server for user access.
• Mode Selection
User selects a mode via the web: Auto, Manual, or Full Brightness.
i. Auto Brightness Mode
Reads ambient light using LDR. Adjusts LED brightness
automatically via PWM.
ii. Manual Brightness Mode
User sets brightness with a slider. ESP32 applies it directly
using PWM.
13. iii. Auto Brightness Off Mode
Ignores sensor and sets LED to full brightness. PWM is fixed
at maximum value.
• Real-Time Monitoring
System checks sensor/user input continuously. Updates LED
brightness instantly.
• Local Web Interface
User connects via Wi-Fi to control modes. Interface runs directly on
ESP32.
Implementation
18. Challenges Faced
Sensor Calibration (LDR)
LDR values were inconsistent in different
environments (e.g., indoor, outdoor, night, tunnel).
Web Interface Communication with ESP3
Difficulty in syncing the website controls with the
ESP32 over Wi-Fi.
Voltage Regulation
Direct battery connection caused voltage instability
for ESP32.
Wi-Fi Connectivity Issues
ESP32 failed to connect reliably to the Wi-Fi network.
19. Future Enhancements
• Integrate more sensors like rain and motion detectors.
• Add automatic high/low beam switching for oncoming traffic.
• Develop a mobile app for remote control and monitoring.
• Implement energy-saving algorithms and solar power support.
20. Conclusion
The Auto Brightness Lamp for Vehicles successfully adjusts headlamp
brightness based on ambient light, improving safety and energy
efficiency. The system also allows manual control via Wi-Fi for user
flexibility. It ensures better visibility in varying conditions. Overall, it’s
a smart, reliable, and user-friendly solution.
