NodOn® Indoor Opening Sensor is a wireless and battery-less sensor that accurately senses the opening and closing movements of doors and windows, and sends the signals to EnOcean controller. The sensor can be used to trigger customized events, like setting off an alarm, sending an email or turning on the lights, whenever an intrusion is detected. Although the sensor comes powered by a solar panel, it provides the flexibility to add an optional CR1216 battery (not included) in case you want to use the sensor in dark areas. It also comes with easy-to-install wall mounting plates for convenient and hassle-free installation.

Nodon Indoor Opening Sensor comes in five colour variants: Wood, Varnish, Black, Alu and White. You can pick the one that matches the ambience of your room from the dropdown above.

  • Accurate Movement Sensing

    When attached to a door or window, the NodOn® Indoor Opening Sensor accurately senses opening and closing movements, and notifies your EnOcean controller instantly about the status. Your EnOcean home automation system can then be configured to trigger customized alerts like sending an email or triggering an alarm based on the status of the panel.

  • Battery-less

    When used in appropriate lighting, the smart opening sensor from NodOn can power itself through its solar panel. However, in case you want to use it in dark areas, the sensor provides an option to add CR1216 battery that can extend the lifetime of the device by 5 years.

  • Easy Installation

    NodOn Indoor Opening Sensor comes with wall mounting plates, which can be installed with screws (not included in the package) or simply using double sided strips at the back of the wall plate.
