The Finger Detection Heartbeat Measuring Sensor Module is a compact biometric device designed to detect and measure a user’s pulse rate through simple fingertip contact. It operates on the principle of optical heart rate sensing, where variations in blood volume under the skin are detected using a light source and a photodetector.
This sensor module is widely used in health monitoring systems, fitness devices, and embedded electronics projects due to its ease of use and cost-effectiveness. It is commonly integrated with platforms such as Arduino, Raspberry Pi, and other microcontroller-based systems, making it highly popular among students, hobbyists, and developers working on biomedical or IoT-based applications.
