Abstract: This paper presents very simple and economical way to monitor and control boilers process used in chemical, pharmaceutical companies remotely with the help of internet. Microcontroller ATmega128 is used to which all sensors and devices are interfaced at its I/O pins. A Stand-Alone Ethernet Controller IC which handles most of the network protocol requirements ENC28J60 is interfaced to the microcontroller using SPI interface and acts as a communication media between microcontroller ATmega128 and remote user. The TCP/IP stack, application source code, and dynamic web page is stored in microcontroller ATmega128. Dynamic webpage is the key element which eliminates physical presence of user in the field and thus saves the labour time and money

Keywords: ATmega128, ENC28J60, TCP/IP, SPI interface, Dynamic webpage
