Hi,
I need help and ideas to realize a new project in my friend’s gym.
In a special gym session him need to collect all data from about 10 heart rate belts from people in the gym room.
So my idea is to buy 10 coded heart belts (like polar) and acquire data wirelessly to send at a processor (like arduino) and collect data to be send to a pc or to another device.
Can someone give me information about a device that can read data from multiple polar coded heart belts that can interface by serial or I2C with an arduino?
Many thanks to all.
