Motion
Motion General Description
The ALTA Wireless Motion Sensor detects movements made by people and animals within a range. ALTA Wireless Motion Sensor+ also measures ambient temperature and relative humidity (RH).
Key Features
Accurately detects occupancy and movement
Software adjustable range (9-ft / 12-ft / 15-ft)
Standard and wide-angle lens options (80° / 110°)
Operating Temperatures: Limited to the operational ange of the sensor body (enclosure and battery)
High-accuracy humidity and temperature measurements(Motion+ only)
Principles of Operation
The Wireless Motion Sensor detects motion, temperature and relative humidity (Wireless Motion+ Sensor), based on a user-configurable time interval or Heartbeat. Using a passive infrared (PIR) motion sensing element, the sensor detects relative changes in temperature caused by warm bodies moving through the sensing area. The Motion+ Sensor is also equipped with a high-accuracy RH/temperature sensing element. Once the sensor detects movement, or if a RH/temperature threshold is crossed, it communicates to a gateway. The gateway will immediately attempt to securely send the message to iMonnit, or another approved data service.
