A sport environment monitoring system based on ARM Cortex-M4 evaluation board and various sensors is designed for purpose of inexpensive

high performance and multiple functions. The system can achieve heart rate

temperature

humidity

air pressure

altitude

longitude and latitude monitoring functions during human body exercise

display the monitoring results in realtime and send short message to cell phone. The design and realization methods of sub-function and functional integration system are introduced separately. Test shows that the system works normally and stably

provides foundation for research on sport health monitoring system. The system can be used as an experimental platform for teaching and scientific research of electronic system.
