Description

This reference design is for a concept demonstration of how a driver's pulse rate, respiration rate, and ECG based heart rate can be obtained from a vehicle steering wheel.  AFE4400 and AFE4300 from TI's biometric family of analog front-ends (AFE), enables acquisition of all three parameters via simple hand contacts on the steering wheel. This reference design also includes a full BLE connectivity design for easy interface to BLE enabled smartphones, tablets, etc

Features
  • Features AFE4400 for measuring pulse from the palm
  • Features AFE4300 for measuring heart rate and respiration rate
  • MSP430F5528 MCU for holding algorithm data for each measurement
  • BLE module connection featuring TI's CC2541
  • This design is tested and provides everthing you need to complete your design including Schematics, Layout and Gerber files, and BOM
