This document describes a student project to design a fire detection sensor. It used an LM35 temperature sensor, Arduino UNO board, and LCD screen. The sensor was simulated in Proteus and was programmed to trigger an alarm on the LCD if the temperature exceeded 60 degrees Celsius, displaying the temperature reading. The project report includes an abstract, circuit diagram, code, and results of the simulation testing the temperature threshold.
