This document describes in detail the design process of a digital temperature monitoring system, developed for Sykes Latin America, S.A. It’s main objective is to allow those in charge of the Information and Technology department to be informed via email and beeper whenever the temperature in the server room exceeds one or several predetermined values. A PIC16F877 micro-controller from Microchip3 is used to gather the temperature from the digital sensors via polling. It also displays the value on an LCD and sends the information through an RS-232 serial link to a PC. A DS18B20 digital temperature sensor from Dallas Semiconductor4 was utilized in this solution and its proprietary serial communication method know as “1-Wire” was used to send the temperature value to the PIC micro-controller. This system employs a Windows application that allows the user to program the different alarms. This application was developed with Visual Basic version 6.0.
