DoorShield

This is a housing for Tony Batey's TinyDuino Wi-fi Door Sensor, for the "Give Your Hardware a Home" contest.

I wanted the design to be simple, elegant, easy to use and install. 

Mounting is easy. There are two screw holes you can use to mount the main housing. The magnet housing doesn't have a mounting hole since it will be sealed, and I didn't want mounting tabs, in order to keep the clean look. The magnet and main housing can be mounted with double stick tape or glue. 

The reed switch, which senses the magnet, can be glued in place. If the magnet needs to be installed away from the main housing, an external reed switch can be wired to the main board. The wires can pass through slots on either end of the housing, and the switch can be mounted anywhere you wish. 

The housing cover is held into place with 4 press-fit tabs. They will hold the cover on securely, yet the cover can be easily pry'd off using a small screwdriver on either end of the unit.

The Arduino boards are held into place by sliding under the left tab, and snapping under the right tab.
