Dispositif de Surveillance de Température basé sur une carte Arduino UNO

Abstract

This project aims to design and build a digital temperature controller based on an Arduino UNO board. The system measures the local temperature using an LM35 sensor, an LCD display, and alerting components, enabling system monitoring. The device functions as an on/off thermostat: when the measured temperature exceeds a predefined setpoint, a safety mechanism is activated. A relay automatically cuts power to the connected heating element, and a red LED illuminates to indicate the alert status. The project uses the Arduino IDE programming environment and is simulated using Proteus software, allowing for functional validation of the circuit before its hardware implementation.
