This paper focuses on classes of remote monitoring and control

applications where important functionality is required at low cost a new

methodology for monitoring and control is proposed where the processing is

based on firmware on an off the shelf microcontroller. Sensing can range across

a number of physical parameters and communication is based on exploiting

existing infrastructure in particular support for TCPIP. Flexibility, low cost,

low maintenance are key drivers-This paper focuses on classes of remote monitoring and control
