Pulse Sensor

The Pulse Sensor is a simple, low-power heart rate monitoring module designed to measure human pulse by detecting blood flow changes through a fingertip or earlobe. It uses an optical sensing method with an LED and photodiode to accurately capture heart beat signals. This sensor is widely used in DIY electronics, health monitoring projects, Arduino, Raspberry Pi, and wearable applications.

Its compact size and plug-and-play design make it ideal for beginners, students, and professionals working on biomedical and IoT projects.
