Next Steps

The variety of home automation projects using capacitive and photocell sensor notifications is expansive. Here are just a few ideas to consider pursuing:

  • Place an XBee+photocell-equipped Arduino, powered by a rechargeable battery pack, in your refrigerator or freezer to detect how often and how long the doors are left open. Use this data to calculate energy expended each month as a result of these encounters.
