General description
The SwimRecorder has been developed
within the SwimMaster
project to record body motion and water pressure during swimming. The SwimRecorder is based on a microcontroller (ATMEGA644), has a 3D-accelerometer (ADXL330), a pressure sensor module (MS5541C) and a light sensor. The data is stored on a uSD card.
Hardware Components
- ATMEGA644 Microcontroller
- 8 MHz external crystal
- 32 kHz quarz for time reference
- 3D-accelerometer (ADXL 330)
- 14 bar pressure sensor module (MS5541C)
- Photodiode (light sensor)
- red and green LEDs
- Reed switch as program button
- Reed switch as reset button
- MicroSD card slot
- Regulated 3.3V Step-Up/Step-Down Charge Pump (MAX1595EUA33+)
- FTDI232 chip for USB connection
Highlights
- Waterproof
- Configurable sample frequency of all sensors
- Synchronization of several SwimRecorder over the charging-station or by light
- Data download via USB over the charging-station
