The term Monitoring system also called data logger is commonly used to describe a self-contained, standalone data acquisition system or device that automatically records, scans and retrieves the data with high speed and greater efficiency during a test or measurement. In this paper, 3 interconnected microcontrollers PIC18F4620, PIC18F262 and PIC16F876A using SPI and UART serial communications has been used. The Program is developed using C programming in MPLAB environment and compiled using MPLAB C 18 C Compiler into .hex file before is written into the microcontroller. LM35DZ and K-type thermocouples are selected as temperature sensors, and SD card and 16×2 dot matrix LCD, mobile phone for GSM modem and DS1307 for real time clock chip are interfaced with the 3 microcontrollers accordingly. The 4×4 matrix keypad uses 8 bit data lines to interface with the microcontrollers.
