So however your cheapest security system is ready to use.

<p>You can simply use a &quot;reed switch door&quot;. It's cheaper, about 1$ and looks well.</p><p>For example: http://goo.gl/N2pI7j</p>
<p>This is mind work not about buying and stuff. </p>
<p>I like the simplicity of this. Of course you can make several of these for different &quot;security zones&quot; and wire them all in parallel with just the one 9v battery all on a single piece of cardboard. Putting an led and resistor across each buzzer would allow you to see which zone is alarming and which is not alarming in the dark. Good project.</p>
