A datalogger that tracks and stores 16 hours of wrist motion data in an effort to create algorithms that can detect eating. The device uses an MSP430 for its microcontroller, an MPU6000 for IMU sensing (accelerometer and gyroscope), an Adesto Dataflash chip for memory (Atmel Serial Flash), and an FT232 UART bridge for communication. This was a Masters project at Clemson University to create a datalogger that tracks and stores 16 hours of wrist motion data in an effort to create algorithms that can detect eating.
See Bite Counter project for more details.
