Motion Sensor


The Wireless Motion Sensor uses Passive Infrared Sensor (PIR) technology to detect the presence of people by measuring changes in infrared light intensity coming from people moving into the sensor's field of view. Detection events are wirelessly transmitted to nearby Cloud Connectors (gateways) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the DT cloud infrastructure. From there, data can be integrated into other services using our REST APIs or viewed directly in DT Studio (web application).
