Design and Simulation of Automatic Temperature Reading System Based PIC16F877

Abstract

The paper is about the design and simulation of an automatic system for temperature sensor using microcontroller. Similar system can be used to measure the temperature of ENGINE CONTROL ROOM. Engine Control Room contains important machineries like ‘Engine control console, operating system, uninterruptible power supply systems etc’. That’s why temperature measurement of the control room is unavoidable. In order to avoid or reduce human effort and for easy monitoring this system will be worthy. The system in this paper used the microcontroller PIC16F877 as the central control unit, LM35 temperature sensor as a temperature source,16x2 liquid crystal display (LCD) as indicator to display the temperature.  The implementation and simulation of the system work has been achieved by using proteus professional software v7.0 and CCS C compiler software to write the equivalent program and generate .hex file for system working.
