Embedded Monitoring Server

This study investigates, designs, and implements an inexpensive application that allows local and remote monitoring of a home. The application consists of an array of sensors for monitoring different conditions in a home environment and also for accessing the devices that might be connected to the system. Only a few sensors are initially involved in this study and information about the temperature level, forced entry detection, smoke and water leakage detection can be obtained at any time from any location with an Internet connection. The application software (coded in C language) runs on an embedded system which is basically a wireless Linksys router running on a GNU/Linux based firmware for embedded systems. Interaction between the sensors and the application software is achieved through an implemented sensor interfacing circuit. The communication with the sensor interfacing unit is done through the serial port, and accessibility of the connected sensors is achieved through a telnet client. The sensors can be accessed from local and remote locations with the sensors giving reliable information. The resulting application shows that it is possible to use the router for other applications other than what it is intended for.
