Pulse Sensor Pulse Heart Rate Module
The Pulse Sensor Pulse Heart Rate Module is a compact optical sensor that detects heartbeats in real time using light reflection from a fingertip or earlobe.
Ideal for Arduino, Raspberry Pi, ESP32, and other microcontrollers, it outputs an analog voltage signal corresponding to each heartbeat for accurate BPM (beats per minute) calculations.
Featuring an integrated photodiode and signal amplifier, the module delivers stable readings even in low-light environments and is perfect for wearable electronics, fitness devices, and biomedical IoT applications.
