Arduino-Based Precise Heating System

Abstract: The present work is aimed at the design and implementation of an Arduino-based heating system that utilizes a temperature sensor and relay for precise temperature regulation. The Arduino processes real-time data from the temperature sensor and controls the relay to manage the heating element, ensuring stable temperature maintenance. Pulse Width Modulation (PWM) is employed to optimize energy efficiency by minimizing temperature fluctuations and improving system stability, offering a more refined control compared to simple on/off mechanisms. The relay provides electrical isolation between the lowvoltage Arduino and the high-voltage heating element, thus reducing the risk of electrical hazards. In addition, the system incorporates programmable safety features that automatically shut off the heating element if unsafe temperature thresholds are exceeded. With its modular design, the system is highly adaptable for a wide range of applications, providing a cost-effective, reliable, and scalable solution for precise temperature control.
