The latest generation of digital body scales provide much more than just weight measurement data. They can provide many different types of information, including body fat, BMI (Body Mass Index), lean mass, muscle mass, and water ratio. As health and fitness become increasingly measurable and connected, a body scale can give valuable information on health and fitness in an easy way. Smart scales can work in conjunction with fitness trackers sharing data via apps connected using Bluetooth low energy technology for example.
ST’s offering provides a broad portfolio of solutions that enable designers to create innovative digital body scales integrating advanced features. Key products include high accuracy and low power motion sensors including embedded event detection features, sensor fusion and software tools that allow to build proprietary algorithms, low power microcontrollers with integrated high accuracy ADCs, power management, and battery management devices to provide the power sources to remote sensing circuities. We also offer NFC technology for easy device provisioning and ultra-low power Bluetooth low energy system-on-chip for seamless communication with smartphones.
This video describes the main components and features of the B-L475E-IOT board and shows a typical use of this platform as an IoT node using AWS (Amazon Web Services) to demonstrate the interactions between that node and a cloud server to build an intelligent system.
