A pulse sensor is an electronic sensor developed to measure an individual’s heart rate or pulse in real time. These sensors typically operate on the principle of photoplethysmography (PPG), detecting changes in the amount of light reflected from or transmitted through tissue due to rhythmic variations in blood flow. The measured analog data is processed digitally through microcontroller platforms such as Arduino, ESP32, and STM32. As a result, pulse sensors are widely used in educational applica
