Displaying sensor status:

I have started work on the web interface to receive sensor data and process it accordingly. I have chosen to set up a local server as this will provide a nice looking interface independent of the OS and simple to modify and update.


Here I'm using a simple image to represent the layout of a small house. Each window and door is protected by an inertia sensors. Should anyone try to enter the house the corresponding sensor will trigger and send a signal via WiFi to the server.

While each sensors is designed to operate autonomously and could activate an alarm directly, the inclusion of a web interface gives us the added ability to further analyse the alarm condition and depending on a variety of circumstances take alternative action...

In its simplest form the web interface might just be used to display information but as you can see from the above example, it could be expanded to almost anything...
