Door & Window Sensor


The Wireless Door & Window Sensor monitors if doors and windows are closed or open based on the presence of a magnet. Upon a change in status, the sensor wirelessly transmits the result to nearby Cloud Connectors (gateways) at a predetermined Heartbeat Interval (HBI) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the cloud via cellular or ethernet connectivity. From the cloud, the data can be integrated into other services using REST APIs and webhooks or viewed directly in DT Studio.

The sensor consists of two parts: a sensor unit and a magnet.  When the magnet is in the presence of the sensor, it will wirelessly send a message to the cloud that updates the status of the sensor to CLOSED. When the magnet is removed, the sensor will send a new message that updates the status to OPEN.

The Door & Window sensor uses HBI to transmit a message notifying the system that it is present and operational, which can be set to 15 min, 30 min, 45 min, or 60 min.

This sensor comes in two versions: EU (Product No. 102736) and US (Product No. 102737), each tailored to meet distinct regional certifications, compliances, and wireless communication requirements.
