$20 Wireless Arduino Home Automation w/ OpenHAB

I created a physical interface for my home automation. Parsing the information on a display requires lots of focus. If you're at home, it's much easier to look at a physical representation of your house. So this physical interface displays information (like if the garage door is opened/closed), and it also let's you close the garage door. Here's some demo videos of how it works.

Complete circuit diagram, code, and explanation is here:

This is a prototype of a dog poop tracker. Working on miniaturizing it. It sets up a virtual fence around the house, warns you if your dog escapes the yard. Also gives you a google map of your dog's poop location, depending on well well your dog's behavior fits in the way it works. Details here:

Here's a prototype for the a laundry room sensor. It uses these sensors:

• Sound Sensor determines when washer or dryer cycle starts and completes
• PIR Presence Sensor used to determine when a completed load is picked up
• Water Detection circuit senses if there is a water leak or overflow, or a flood in the basement.
• light sensor circuit from the Uber sensor is used to determine if the laundry room light is left on.
• Temperature/Humidity sensor - because it's so cheap to add another sensor

The idea is to move the notification that a wash/dry cycle is complete - move it from the basement to the living room or kitchen, where you're more likely to make use of that signal anyways. It also keeps track of whether the wash has been picked up.

This is the interface for the sensor on the smart phone/tablet:

Integrated several different sensors into OpenHAB via my wireless Arduino gateway.  This tupperware sensor monitors lights, dog barking, fire, smoke, flammable gas, temperature, and movement.

Added mongodb for historizing and making charts of sensor data. 

Updated sketches to reflect latest changes, better commented.  Added schematic for battery powered Arduino used in Mailbox example.

Finally finished a video demo of a wireless Arduino mounted under a mailbox.  Wow, video demos take all day to make.  Still not perfect, but good enough for show.
