Our Heart Rate Monitor Experiment Kit gives you all the essential pieces to make a human heartbeat an input to your microcontroller project.
The Polar Wireless Heart Rate Monitor and Receiver can communicate together with up to an 80 cm reception range. See the Downloads below for the manufacturer's specifications. We've added a few items to facilitate the connection to your microcontroller and to add visible and audible output to your project.
This transmitter and receiver pair were included in the Inspiration Kit for the 2013 National microMedic Contest. They proved to be such popular ingredient for the winning biomedical device projects that we are offering them again in this kit.
