Heart Rate and Pulse Waveform

datalogging sensors


Data Harvest

Product Description


Continuously monitor the heart rate at rest and after exercise. Simple finger clip design uses infrared to monitor blood volume in fingers and calculate heart rate. 


Teaching applications:
  • Pulse and heart beat
  • Recovery times
  • Effect of exercise on heart rate
  • Baroception – change in rate due to standing, sitting and lying
  • Heart rate from wave data

Extension and advanced ideas:
  • Combine with ECG and stethoscope to study whole heart cycle
  • Look for Dichrotic notch
  • Time between beats
  • Measure pulse changes with exercise over time

Heart Rate: 0 to 200 Beats per minute
Pulse Waveform: ±2000 mV



  • Uses infrared technology, strong infrared sources may interfere with data collection (e.g. bright sunlight)
  • Spare finger clips available (3147SPP)
  • You need to stay reasonably still while using this sensor. If exercising use the Polar Heart rate skin contact sensor instead (3148)





Pulse Heart Rate (Biology (11-14) ebook)
This simple experiment uses the alternative waveform range of the Heart rate / pulse sensor. The waveform range produces an output based on the blood volume at the sensor. The result is a trace of that shows the change in blood volume as a pulse waveform. Ideal for counting pulses, time between pulses etc.

Chair Gym (Biology (11-14) ebook)
This simple activity uses the beats per minute range of the Heart rate / pulse sensor. The activity shows how the heart responds to exercise and position (baroception) without the need for full on gymn lessons!

Choc Heart (Biology (11-14) ebook)
This simple experiment uses the beats per minute range of the Heart rate / pulse sensor. It shows how a chemical can override the hearts normal control and impose a pattern of heart beats of its own. Could be used to introduce how non pharmaceutical drugs take over the control of the body

Measuring heart rate. (Biology (14-18) eBook)
This simple experiment uses the waveform range of the heart rate / pulse. It produces a trace of peaks and troughs, each peak is the point of the heart beat. Counting peaks and feeling the heartbeat links heartbeat to pulse. A good introductory activity for circulation and fitness work.

The armchair gym (Biology (14-18) eBook)
An activity to show that work into pulse, heart rate and activity does not have involve mass gymnastics. Can also be used to show principles of baroception in maintaining blood pressure.

Effect of Chocolate on heart beats (Biology (14-18) eBook)
This simple experiment uses the beats per minute range of the Heart rate / Pulse waveform sensor. Displayed data is as beats per minute. How does chocolate change the heart rate? 

Heart Rate and pulse (Biology (14-18) eBook)
Use a heart rate sensor to record pulse (beats per minute) or waveform. Use to learn how to use the basic apparatus and understand the results. Good introductory activityr does it make any difference?

Heart Monitoring, sound, ECG, pulse (Biology (14-18) eBook)
This is a more complex investigation, but well worth the effort. It offers many teaching possibilities. Record heart sound, ECG and uncalibrated pressure profile in one data set. Good for analysis and understanding the linked data of a heart beat.



Pulse - measuring heart beats and rates. (Science in Sport (11-18) eBook)
This exercise is best suited as an introduction / refresher to basic calculation and measurement of heart rate. The infrared finger clip sensor is not really suitable for detecting changes of pulse with activity, but provides an excellent stimulus lesson for discussion about heart rates and what they can mean for fitness and performance.

Pulse measuring change (Science in Sport (11-18) eBook)
This simple experiment uses the beats per minute range of the Heart rate sensor. This range automatically monitors the time of each pulse and converts it to a beats per minute value.

Recovery rates and exercise (Science in Sport (11-18) eBook)
Classic basic work on recovery rates, if there is one interaction between sport and science to be remembered it is this one!

How does chocolate affect my heart? (Science in Sport (11-18) eBook)
Performance enhancing compounds are universally frowned upon in sport. Here is a simple activity to start a discussion about the morality. Some people find that chocolate has controlling influence on heart beat stability - are you one of them? would you take chocolate before a competition knowing it changes you?




Not only exercise changes heart rate (Science At Work (11-16) eBook)
Check the heart rate over a series of events from relaxing to watching a scary movie! how does the hear respond?
