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 @video).
