Exercise Heart Rate Sensor
The Exercise Heart Rate Sensor monitors a person’s heart beat. Similar to electrocardiogram (EKG), this sensor monitors the electrical signal of the heart. Each time the heart beats, an electrical signal is generated. This signal is measured at the surface of the skin by electrodes embedded in the chest belt of the sensor. By graphing this signal the heart rate can be determined. The transmitter belt is worn just below the chest and held in a place by an elastic strap. The transmitter detects each heart beat through two electrodes with ECG accuracy and transmits the hear rate information to the plug-in receiver with the help of a low frequency electromagnetic field.
The sensor can not be directly connected to a PC. Its output signal appears on three wires. To connect to a PC an interface board is required, such as an Arduino or Wiring board. The heart rate sensor was purchased from the University of Amsterdam’s Centre for Microcomputer Applications. See their website for other sensors.
