Arduino-Based Precise Heating System

Abstract

The present work is aimed at the design and im¬plementation 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, en¬suring 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 low-voltage 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.

Introduction

he study presents an Arduino-based heating system using a DS18B20 digital temperature sensor for precise temperature monitoring and control. The system employs Pulse Width Modulation (PWM), a solid-state relay for electrical isolation, and safety features to prevent overheating. It features user interaction through a keypad to set target temperatures, with real-time feedback displayed on an LCD screen.

The system architecture includes a heating element controlled by the Arduino via the relay, the DS18B20 sensor for accurate temperature measurement, an LCD display for status updates, and a keypad for user input. The Arduino processes sensor data, manages heating by turning the relay on/off based on temperature comparison, and handles input timeouts.
