The Smart Data 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 smart sensor’s
field-of-view. Detection events are wirelessly transmitted to nearby Cloud Connectors (gateways) via
SecureDataShot™ technology. Cloud Connectors relay sensor data to the cloud infrastructure. The relayed data can be viewed in the Smart Data dashboard or exported to other services via webhooks or developer APIs.
Room Occupancy Detection
The Wireless Motion Sensor uses Passive Infrared Sensor (PIR) technology to detect the presence of people in a room by measuring changes in infrared light intensity coming from people moving into the sensor’s field-of-view. When the sensor detects presence it will send a MOTION DETECTED event to the cloud and start a pre-set Activity Timer. If the sensor continues to detect the presence of people before the Activity Timer expires, the timer will restart. When the Activity Timer expires, the sensor will send a NO MOTION DETECTED event to the cloud.
Independent of occupancy events, the sensor will periodically transmit Network Status Events to the cloud containing connectivity information, so that the system can know that the sensor is online and functional.
Features
- 360° field of view – up to 14m (46ft) detection zone
- Up to 10-year battery life with 2xAA batteries
- Long wireless range – up to 100 meters (328 ft) indoors
- User Configurable Settings: determines how close a person have to be to the sensor, as well as the how long the person has to stay within a zone before a detection event is triggered. In the highest sensitivity mode, the sensor will trigger if people quickly grace the edge of the detection zone.
- Activity Timer: how long (in minutes) a zone is considered occupied after the most recent ‘People detected’ event. The longer the Activity Timer is, the longer the battery will last.
- Counting Mode: instead of sending an MOTION DETECTED or NO MOTION DETECTED event, the sensor can be set to count the number of detection events. The updated count is sent with each Network Status Event (every 30 minutes). Please note that the sensor is not capable of accurately counting the number of people in a room. It is only capable of counting the number of detection events.
