The ‘Fixture-Integrated Sensor’ from Murata can be integrated into a wide range of luminaires, allowing users to configure and control lighting network from a smartphone
Bluetooth mesh allows devices within a Bluetooth LE network to communicate directly with companion devices without recourse to a central hub device. Such a system extends communication range, flexibility, and reliability. Key applications for Bluetooth mesh include professional lighting installations, back-ends for managed beacons, and industrial monitoring.
Nordic’s nRF52832 SoC is a powerful multiprotocol SoC ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications. The nRF52832 combines an 64MHz, 32-bit Arm® Cortex™ M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software) featuring -96dBm RX sensitivity, with 512kB Flash memory and 64kB RAM. The SoC’s powerful processor and generous memory can support the sensor’s complex mesh software, while the radio’s sensitivity ensures good range.
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 Nordic’s nRF52832 SoC because of the capabilities of the Arm processor and the large memory capacity,” says Takeshi Sato, General Manager of IoT Business Promotion Department, Murata. “The availability of technical information from Nordic is also impressive.”
