Rather than requiring costly and time-consuming hardwiring to a central location, the mesh network offers fast and flexible operations that can be continuously adjusted. The ability to broadcast operating parameters from a smartphone and easily update functionality also makes scalability easier for facility owners and operators.
The Dimming PIR Occupancy Sensor provides 360° of coverage at mounting heights up to 40 feet. The sensor also provides bi-level dimming via 0-10 V control, which complies with many energy code requirements and offers greater energy-efficient performance than simple on/off control. The IP65 rating makes the sensor ideal for wet locations, such as parking structures, nurseries, or loading docks.
Nordic’s nRF52832 multiprotocol SoC combines an 64MHz, 32-bit Arm® Cortex™ M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96-dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.
“We selected Silvair’s SIG-qualified Bluetooth LE mesh stack (running on Nordic’s nRF52832 SoC) as it aligns fully with the Bluetooth mesh specification, offering the full potential of interoperability for customers and the widest range of product choices both in fixtures and other control devices,” says Stephen Zhou, Vice President of McWong.
“In addition, the McWong team was impressed with Nordic’s technical documentation and its reputation as a proven industry leader for Bluetooth LE implementation.”
