The tamper-proof data logger weighs only 60g, and is powered by a 290mAh Li-ion battery, providing up to six weeks of continuous operation, thanks in part to the ultra low power characteristics of the Nordic SoC. The nRF52832 SoC has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs. The result is a Bluetooth LE solution which offers 58 CoreMark/mA, up to twice as power efficient as competing devices.
Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines an 64MHz, 32-bit ARM® Cortex® M4F processor ARM M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. When launched, the SoC was the world’s highest performance single-chip Bluetooth LE solution.
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 Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.
“We evaluated different platforms from various vendors before selecting Nordic’s nRF52832 SoC,” says Stefan Weber, modum.io’s COO, overseeing product development. “On one hand, the Nordic SoC meets our technical requirements in terms of performance, energy consumption, and interfaces. On the other, the easy-to-use and professionally documented Software Development Kit allows us to bring our product to the market faster than with any other platform. For us, using the SoC and associated Software Development Kit was a ‘no-brainer’.”
The temperature logger will be commercially available from Q1 2018.
