Hicling Technology's Cling VOC health bracelet uses Nordic Semiconductor's nRF51822 SoC to monitor and report on a wide range of health data wirelessly, including heart rate, body temperature, activity and sleep

Nordic Semiconductor Company announces health-based concepts and can wearTechnology of Shanghai John Pro Technology (Hicling Technology) has chosen Nordic many award-winning nRF51822 Low power consumption bluetooth(Bluetooth®low Energy) (formerly known as Bluetooth Smart) system-level chip (SoC) for its next-generation cling VOC health bracelet. This multifunctional bracelet and smart watch is equipped with a range of sensorTo track health data, including heart rate, body temperature, activity, and sleep, a pair of MOX multi-sensor gas sensors based on MEMS technology are used to monitor indoor air quality and alcohol concentrations in the user's blood. These professional grade sensors are capable of detecting volatile organic compounds (VOC) in the air, with a precision of up to ten ppb (part per billion), and 1mg/100ml blood alcohol concentrations for a range of personal and enterprise safety applications and end users. In the cling VOC bracelet, the nRF51822 Soc wirelessly synchronizes the captured data to the iOS or Android cling app. With the cling app's dial, users can monitor the recording of heart rate and skin temperature and see statistics on their activity (steps, distance, and calories burned). The app also provides sleep analysis data, as well as a holistic health assessment based on user lifestyle and personal records. This wearable product features a 9 x 18mm bracelet form factor, powered by a 65mAh lithium polymer (Li-pol) battery, can be used up to six days after charging, and a charging time of one hours, thanks to the ultra-low Nordic SOC Power ConsumptionCharacteristics. "Nordic is known for its ultra-low-power short-range wireless products, and nRF51822 devices are the best choice for our low power and performance targets for cling VOC bracelet products," said Chen, founder and CEO of John Pro Technology. "Nordic's nRF51822 is a powerful and flexible multi-protocol SOC product for low power Bluetooth and 2.4GHz ultra-low power wireless applications. The nRF51822 is built around a 32-bit ARM®CORTEX™M0 CPU with 256KB/128KB flash memory and 32kb/16kb RAM. This one EmbeddedThe 2.4GHZ transceiver is fully compatible with the latest version of the Bluetooth specification bluetooth® 4.2, which includes low power Bluetooth.
