Data Harvest Heart Rate & Waveform Sensor – 3147

The Data Harvest Heart Rate & Waveform Sensor 3147 enables students to explore how physical activity, emotional stress, and relaxation affect the body. Using a sensitive plethysmograph clip (pleth), the sensor can be attached to a finger or earlobe to measure heart rate (beats per minute) and pulse waveform (blood flow).

This dual‑function sensor gives learners immediate, real‑time feedback, making it ideal for investigations into the cardiovascular system, exercise science, biofeedback, and human physiology. It is intuitive for pupils of all ages and integrates seamlessly with Data Harvest’s data‑logging equipment.

Key Features

• Measures heart rate in beats per minute (BPM)
• Captures pulse waveform for blood‑flow analysis
• Comfortable pleth clip attaches to finger or ear lobe
• Provides real‑time, accurate physiological data
• Ideal for demonstrating how stress, exercise, and relaxation affect the heart
• Fully compatible with Data Harvest SmartQ systems
• Durable and classroom‑friendly design

Ideal for School Science Lessons & Physiology Investigations

Perfect for KS3, GCSE, and A‑Level biology, the Heart Rate & Waveform Sensor helps students understand core concepts in human physiology and health science. Its clear and engaging data display makes it suitable for individual, group, or whole‑class demonstrations.

• Investigating how exercise intensity affects heart rate
• Exploring stress responses and relaxation techniques
• Analysing pulse waveforms and circulation patterns
• Supporting practical work in biology, PE, and health sciences
• Demonstrating biofeedback and monitoring changes over time

Engaging, accurate, and easy to use, this sensor provides an excellent hands‑on introduction to the study of human physiology and cardiovascular function.
