Security systems don’t have to be complex. Everyone can use a bit imagination and build one around a house. Ken wanted to take control of his house security management and build a simple model of security system. The center of controller is a JeeNode board from JeeLabs. This is small Atmega328P based board with wireless adapter.
Security system consists of 3 magnetic door sensors, single panic push button, temperature sensor and motion sensor. Hen even worked out a SketchUp model of home plan where he is able to indicate which of sensors has been triggered. Project is still in development and new features like keypad should appear soon.
