Data Logger Heart Sensor

Pupils of all ages are keenly interested in how physical and mental stress affects their heart rate. The sensing clip (pleth) can be attached to a finger or ear lobe to measure either blood flow (pulse waveform) or heart rate (beats per minute).

Activities:

• Heart rate changes due to activity

• Recovery rate

• Pulse rate

• Effect of food (chocolate) or mild stimulants (caffeine)

• Remote logging set up from the computer

• Effect of music on pulse rate
