Wireless Motion/Lux Sensor
WS-ML-902

As part of Carrier’s wireless sensing line, wireless motion/lux sensors are used to detect motion and light in a space. Because there are no wires to run, they can be added to your building easily.

Wireless sensors work in conjunction with a wireless adapter, which enables wireless communication between the sensors and an i-Vu® BACnet controller in the space. By sensing motion and lighting levels wirelessly, our i-Vu controllers can make smart decisions to optimize the control of heating, cooling, and lighting systems in the building, providing optimum occupant comfort and energy efficiency.

Ideal applications for the wireless motion/lux sensor include occupancy-based lighting and temperature control, as well as indoor daylight harvesting.


Product Features

  • Communicates on the Rnet sensor network via a wireless adapter
  • Can be installed up to 60’ away from wireless adapter
  • Enables wireless sensing on new or retrofit projects
  • Wireless software included for quick and easy sensor pairing

Comprehensive Capabilities

  • Passive infrared motion sensor ensures reliable detection of occupant presence for occupancy-based control
  • Integrated light sensor for daylight harvesting strategies
  • Wireless and battery-less space sensors (assuming sufficient lighting exists in space)
  • Maintenance-free capacitors power the sensors during unlit periods for up to 4-days without a light source
  • No repeaters or amplifiers required for zone-based applications
  • Integrates seamlessly with i-Vu® system alarming for proactive monitoring of important sensor conditions, including:
    • Sensor charge level
    • Sensor signal strength
    • Sensor offline
  • Can co-exist on Rnet with Carrier’s wired ZS sensors
  • Single-zone controllers can support a total of 5 sensors
  • Multi-zone controllers can support up to 15 sensors
Power supply Solar harvesting, internal energy storage
Supplemental battery A 1/2 AA 3.6 V 1200 mA battery is included to supplement power during commissioning and for low-light conditions
Maximum operating life Up to 4 days with no light power or battery
Time to fully charge depends on available lux
Full charge in 8 hours @ 1000 lux or 24 hours @333 lux
