Smart Home Control System

My Contributions

Heating System:

  • Designed a digital thermostat using an LM35 temperature sensor and servo motor to simulate radiator valve control.

  • Implemented serial feedback and threshold-based logic for real-time heating control.

  • Suggested non-blocking timing (millis()) for improved responsiveness in future iterations.

House Alarm System:

  • Built a motion-triggered alarm with password entry, window/door status checks, and alarm activation via buzzer.

  • Integrated proximity and IR sensors for detection logic and serial feedback for system states (e.g., “System Armed”).

  • Resolved wiring and sensor calibration issues during development and testing.

Menu Control Structure:

  • Created a centralised menu system using switch-case logic for seamless navigation across all subsystems.

  • Implemented cleanup functions and initialisation checks to prevent pin conflicts and actuator overlap.

  • Designed for scalability, allowing new subsystems to be added without rewriting the core code.

Team Contributions

Panic Room System:

  • Developed a secure locking mechanism using a potentiometer-based three-digit code, dual-button control, and servo motor for bolt simulation.

  • Added visual feedback via LEDs and error handling for incorrect codes.

Heat Curtain System:

  • Simulated oscillating heat curtain flaps controlled by force sensors and a DC motor via an H-bridge.

  • Calibrated sensor thresholds and implemented non-blocking timing for realistic motion control.

Dual-Zone Lighting System:

  • Used LDR and ultrasonic sensors to control two separate lighting zones on a 12×8 LED matrix.

  • Implemented automatic lighting triggers for ambient light and motion detection, with serial feedback for debugging.
