This is a hardware-based system designed to assess and compare the effectiveness of a commercially available LDR and an in-house ARCI-developed LDR. By automating the switching of street lights based on ambient light conditions, the system aims to optimize energy usage and demonstrate sensor performance. Built using an Arduino microcontroller and supporting components, the setup allows for long-term data collection and analysis.

Key Features

  • Dual LDR Evaluation: Compares performance between a commercial LDR and an ARCI-developed alternative.
  • Embedded Automation System: Based on an Arduino microcontroller for sensor input processing and system control.
  • Light-Based Switching: Automates street light operation in response to real-time ambient light levels
  • Signal Amplification: Uses a sensor signal amplifier for improved accuracy and sensitivity.
  • Real-Time Clock (RTC): Enables time-stamped logging of switching events and light level readings.
  • Data Logging: SD card storage allows for continuous performance tracking and archival.
  • Solid State Relay (SSR): Provides efficient and reliable switching of the street light circuit

Potential Applications

  • Urban Street Lighting: Enhances energy efficiency by automating light activation based on actual lighting conditions.
  • Smart Cities: Integrates into intelligent lighting systems for adaptive control.
  • Campus and Institutional Grounds: Automated night-time lighting for safety and cost savings.
  • Rural Electrification Projects: Low-cost, autonomous lighting control solutions.
  • Sensor R&D and Benchmarking: Supports development and evaluation of new LDR sensor technologies.
