ELA Blue Puck Mag - Bluetooth Magnetic Door Sensor

  • Blue Puck Mag Bluetooth Door Sensor

    The Bluetooth Low Energy-enabled Blue Puck Mag sensor is tiny. It is 100% autonomous and durable, allowing for the secure transportation of goods by monitoring the opening and closing of truck doors.

    Door opening detection

    Detect the opening of truck doors to secure the movement of commodities. Thanks to Bluetooth magnetic sensors, the driver receives a real-time notification on his smartphone when the door is opened in an unauthorised location, helping combat theft and aggression.

    How does a door sensor work?

    The magnetic detection sensor uses magnetism to detect when doors are open. The sensor is attached to a fixed part, such as a door frame, and the magnet is attached to a moving part (e.g., the door). They must be close together.
    This Bluetooth-connected sensor transmits at regular intervals to communicate its "state," 0 or 1, which corresponds to an "open" or "closed" status. The following GPS Trackers can act as a gateway the (G120, G150, G70 BLE, Remora3 BLE, or Oyster Edge BLE, Oyster3 BLE) picks up the signal and transmits it back to the platform servers.

    When the sensor and magnet are separated by more than 2cm, the sensor's state changes (from 0 to 1), indicating that the door is open. Suppose this change occurs in an unauthorised area or geo-fenced location. In that case, notifications can be sent to the account administrator informing them of the change in status or door open/close state. The driver or business will receive a real-time alert notification via the Telematics Guru smartphone app notifications or email alerts.
