Temperature-Controlled DC Motor System

This project demonstrates a temperature-controlled DC motor system using :

• PIC18F452 microcontroller.
• LM35 temperature sensos.
• DC motor.
• LM016 LCD for displaying temperature and motor speed.

The motor's speed is adjusted based on the temperature measured by the LM35 sensor.

Project Components

Microcontroller: PIC18F452 Compiler: C18 Simulator : Proteus Temperature Sensor: LM35 Motor Type: DC Motor LCD Display: LM016 (16x2)

Project Description

This system monitors the ambient temperature using the LM35 temperature sensor. Based on the measured temperature, it controls the speed of a DC motor as follows:

1)-Temperature Range 40°C < T ≤ 150°C: The DC motor runs at high speed.

2)-Temperature Range 25°C < T ≤ 40°C: The DC motor runs at medium speed.

3)-Temperature ≤ 25°C: The DC motor is turned off.

NOTE :

This project is for learning and haven't yet implemented in real hardware but it works and give good results in proteus simulator(check vedio).
