About this item

The DFRobot Gravity Heart Rate Monitor Sensor for Arduino is an easy-to-use, plug-and-play sensor designed to measure human heart rate through optical technology. Using a photoplethysmography (PPG) method, it shines a light onto the skin and measures changes in light absorption caused by blood flow, allowing accurate heart rate detection. Ideal for beginners and developers alike, the sensor works seamlessly with Arduino, offering real-time pulse monitoring for fitness tracking, wearable health devices, and biometric experiments. The module includes a Gravity interface, making wiring straightforward and eliminating the need for soldering or complex setups. This sensor is designed for non-invasive fingertip or earlobe use, providing reliable performance with minimal setup. It filters out noise and provides clean analog output, which can be read and processed using standard Arduino ADC pins. Its compact form factor, low power consumption, and ease of use make it suitable for portable and battery-powered applications. Whether you're building a personal health monitoring system, experimenting with biosignals, or developing wearable tech, this heart rate sensor offers a stable and affordable solution to integrate pulse data into your projects.
