3D Model Design of Concept #Wearable Device
SiLabs launched the BTLE sensor puck v2.0, I used it to prototype a music recommendation engine based on your heart-rate using Spotify API.
When your heartrate is high, it recommends upbeat music, when it's low, it recommends calm soothing music and visa versa.
Silicon Labs’ Si114x Optical Sensors
The coin-cell battery operated SENSOR-PUCK is controlled by an EFM32™ energy friendly MCU. A Bluetooth Low Energy (BLE) module is used to broadcast sensor data to iOS or Android smartphones with the downloadable SENSOR-PUCK app. Place your finger tip over the Si1147 sensor to measure heart rate. Environmental sensing of UV Index, ambient light, relative humidity, and temperature is also provided. For power management, the board features a Touchstone TS3310 boost DC/DC converter.
