Design and Implementation of Microcontroller based Temperature Monitoring System

Abstract

Temperature monitoring system plays a very important role in modern liquid industrial process especially where temperature monitoring is impossible through traditional methods. In this paper a design and implementation of temperature monitoring system using ATmega328 microcontroller has been proposed. The proposed system consists of two different parts. The first part is temperature monitoring system and the other is GUI interfacing between temperature monitoring system and computer as temperature data storage. The monitoring part is composed of an ATmega328 microcontroller, temperature sensor LM35, alarm buzzer, a LED and a LCD. The microcontroller is programmed in embed C language using Arduino Uno software to read data from temperature sensor LM 35, convert and display in digital form on LCD. Moreover, this part also indicates whether the temperature is low, high or safe by LED
light and alarm buzzer. The second part is GUI interfacing between temperature monitoring system and computer which is performed through visual basic
programming using Microsoft visual basic software. The function of this part is to store and display the temperature values and their waveform along with time and date on computer.
