how the pulse changes
The speed of your pulse changes as you go about your day. It changes as you sit, walk or exercise.
It is quite easy to record your pulse using the computer. You used to connect yourself to a pulse sensor and the sensor sent readings to the computer.
Today you might want to do that with a smart wristband. What is more, you can measure your pulse continuously, and see changes over time. You might start by measuring your pulse over several minutes. You can then choose an idea to investigate, for example:
How does your pulse change during and after exercise?
How do your results compare with other people’s results?
Connect the pulse probe to your body or finger or wrist.
Start recording and record for 10 minutes. The sensor may need a minute before it gives a steady reading.
