Supplied with an ear/thumb sensor and Heart Rate Sensor Adaptor, students can learn how physical and mental stress affects their heart rate.
Note: Vu+ data logger required
Measuring Heart Rates:
The Heart Rate sensor sensing clip (pleth) holds an infrared LED that shines a light through either a finger or ear lobe onto a light sensitive detector. As the amount of light transmitted varies with the flow of blood, the sensor can record either blood flow (heart waveform), or heart rate (beats per minute).
Use the Vu heart Rate Sensor to investigate a number of scientific experiments such as:
Works best if the test subject keeps the finger with the sensing clip absolutely still.
