The BleBox openSensor opening sensor detects whether a window, door, or other opening structure is open, tilted, or closed using magnetic induction at two points. It connects wirelessly via μWiFi and WiFi and can be integrated with other BleBox devices for automation scenarios, while sending notifications to your smartphone. Its cable is 2 m long.

It is suitable for windows, skylights, balcony doors, patio doors, stables, animal enclosures, electrical panels, and IT cabinets. The two open-collector outputs are controlled via ground and protected against short circuits and reverse polarity.
