2 AAA 1.5V batteries (included)
Radio communication
The HDOORPOSITION sensor activates when the magnet is close to it and sends a radio signal to HONOADOOR. Install the magnet on the bottom of the door and the sensor at the same height on the wall to know when the door is completely closed. Install another HDOORPOSITION sensor on the top to know when the door is totally open. It can tell the difference between closed door, opening, open, and closing.
