Elegant. Intelligent. Smaller still. The 2nd generation Aeotec Door / Window Sensor provides your Z-Wave network with the intelligence required for a modern home automation and security system. And it does it all in a smaller, more elegant design crafted to suit any home’s decor. The Door & Window Sensor finds out something very simple – whether a door or a window, or in fact any object in your home, is open or closed. But there’s power in simplicity. Power that allows you to inform the rest of your Z-Wave network about your selected doors and windows. Like a thermostat lets your heating and cooling systems know what they should do next, Aeotec’s Z-Wave Door & Window Sensor does the same. Perhaps an open door means that your lights should turn on and welcome you home. Perhaps an open window means that an alarm should be triggered. Whatever it means to your home, with door and window sensors installed, your Z-Wave network will have both the power and the intelligence to do it.
