Hi guys,
I was wondering if I could get your opinion on how I should approach this project.
My project is basically to create a home alarm using XBee technology and Arduino. My "end components" (motion sensors, 'magnetic door open detectors', water level detectors), must be able to communicate to a base station wirelessly.
My question now is how can I minimize the cost of my end components? I know I will require an XBee module, Arduino board and the actual sensor. How can I approach this project in the most cost effective manner?
Thank you for any advice!
