DC Motor Control using Temperature Sensor & 8051 Microcontroller

Microcontroller are widely used in electronics gadget and are one of the key element in developing any project and thus this project used 8051 microcontroller and will help in teaching about interfacing of temperature sensor with ATMEL microcontroller by means of ADC, to display the temperature on a 16x2 LCD and to rotate a DC motor at two different speeds at various temperatures. This project on digital thermometer is good implementation of project using microcontroller.

In this project, we have now given a new temperature feedback to your temperature sensor which in turn modifications this to your similar a new analog voltage which is to be directed at a ADC. For you to convert this analog files in to a digital waveform, determined by a new reference voltage and that is fed to your microcontroller this temperature are going to be viewable with a 16x2 LCD. Control of DC motor is done in such a way that it runs on two different speed depending upon the temperature.

Recommended Project: Microcontroller Projects with Programming and Source Code

For implementation of this project Proteus software is used which is a software for microcontroller simulation, schematic capture and printed circuit board design and is developed by Lab center electronics.





This project report contains the circuit diagram and its analysis along with the microcontroller programming for help. In this project LCD and ADC0804 interfacing with Atmel AT89C51 was studied and implemented on Proteus and same was assembled on a PCB. Thus we have successfully made a dc motor to run at different speeds by varying temperature. You can use this project for your reference and study work.
