"Customer Wearables nRF52840 Bluetooth 5 Thread Zigbee Atmos diving watch"

The ‘ATMOS Mission One’ diving watch employs Nordic’s nRF52840 SoC to act as the main control chip for the device, processing complex sensor data and providing wireless connectivity

Nordic Semiconductor today announces that ATMOS, a Taiwan-based diving technology company, has specified Nordic’s nRF52840 Bluetooth® 5/Bluetooth Low Energy (Bluetooth LE) advanced multiprotocol System-on-Chip (SoC) to act as the main control chip for its ‘ATMOS Mission One’ diving watch, as well as provide the device with Bluetooth LE connectivity.

The Mission One diving watch features a range of sensors—including a digital compass, gyroscope, accelerometer, thermometer, barometric altimeter, depth sensor, and GPS—to enhance the diver experience and safety. The Nordic SoC’s powerful 64MHz, 32-bit Arm® Cortex® M4F processor provides ample computational power to run the complex sensor algorithms, allowing the watch to precisely track and calculate decompression, record specific dive information, and create an overall dive profile. The sensor data is stored in the nRF52840 SoC’s generous 1MB Flash memory while a dive is in progress, which can then be wirelessly synced to the iOS- and Android-compatible ‘ATMOS’ app on the user’s Bluetooth 4.0 (or later) smartphone once the diver has resurfaced.

"The Mission One’s range of sensors demanded an SoC with a very powerful processor, and the nRF52840’s Arm M4F’s Floating-Point performance offered us a significant competitive advantage
Chang Youyu, CEO at ATMOS"
