The BVP Sensor is used for measuring Blood Volume Pulse (BVP) or Heart Rate (HR). This sensor is alos known as a PPG (photoplethysmography) sensor and uses a light-based technology to sense the rate of blood flow as controlled by the heart beats. By using the BVP Sensor the Heart Rate Variability (HRV) can be acquired: this refers to the rise and fall of heart rate synchronized with breathing (faster on inhale, slower on the exhale).

The magnitude of this systematic variability seems to reflect a healthy alternation between two autonomic influences of the heart beat: sympathetic and parasymphathetic. By calming one's emotional state and by making the breathing slower and more regular, the HRV can be increased, at least temporarily.

This sensor is usually placed on a finger of the non-dominant hand. Make sure not to move the sensor too much since this will influence your signal and create artifacts/noise.

Use the Respiration Sensor in combination with the BVP Sensor in order to monitor both breathing and heart rate for several biofeedback applications.

Although the BVP sensor is a very efficient way of quickly measuring heart rate, you can alternately do an ECG/EKG with our EXG Sensor. Because of carbon technology and active noise cancellation, this sensor is less susceptible to artifact. The BVP sensor is often preferred though because of ease of use and efficiency.

The specifications of the BVP Sensor are:

  • Unit Beats per minute for heart rate

  • Derived Parameters   Heart rate and relative blood flow

  • Connector Aluminium brushed medical grade ODU connector

  • Range 40-240 beats/minute
