Abstract
This project aims to propose and implementation of DC motor speed control based on the Temperature and Pressure sensing deviation. This project is mainly concerned on DC motor speed control system by using PIC 16F877A microcontroller. Motor speed can be control with variable resistor. Variable frequency drive uses power electronics vary the frequency of input power to motor, thereby controlling motor speed. The complete system consists of an ac voltage input that is put through a diode bridge rectifier to produce a dc output which across a shunt capacitor In good-quality speed control is one of the reasons for the strapping aggressive position of DC motors in the modem industrial applications. So, this programming device can be used any motor to control their speed. Temperature sensing device display the temperature of any place. At the heart of the circuit is the LM35, MPXV5050V and PIC 16F877A microcontroller which controls all its functions. LM35 is a precision temperature sensor with its output comparative to the temperature (in ºC). A temperature sensor LM35 is used for sensing the temperature of the environment and the system displays the temperature on an LCD. The simulation of the system has been done on Proteus Professional Software. In this project, PIC 16F877A microcontroller can control motor speed at desired speed with temperature sensing unit and pressure sensing unit which is used to display the temperature and pressure of its take place.
