The Polar Heart Rate Receiver is designed to receive heart beat signals from compatible Polar heart rate sensors such as the T34. Together, the sensor and receiver provides a low-cost and convenient heart rate monitoring system that can be connected to most any microcontroller.
The Heart Rate Receiver is a stand-alone module, with on-board connections for power (3.3 V to 5 V), ground, and signal. It wirelessly interfaces to a compatible Polar coded or uncoded sensor transmitter. The output pin simply pulses high when a heartbeat is detected. This module:
-> Receives heart beat signals from a compatible sensor transmitter
-> Indicates a received heartbeat signal using a LOW/HIGH output signal
-> Wirelessly interfaces to transmitter with a range of up to four feet
