Features  

• Original Pulse Sensor (pulsesensor.com) – 16mm diameter  
• Plug-and-play with Arduino, ESP32, Raspberry Pi & STM32  
• Optical heartbeat detection using green LED + phototransistor  
• Real-time BPM (beats per minute) output via analog signal  
• On-board amplifier & noise cancellation circuit  
• 3-pin connector: VCC (3.3V-5V), GND, Signal  
• Easy to wear on finger or earlobe with Velcro/clip  
• Open-source Arduino library & example code available  
• Low power consumption (<5mA)  
• Compact & lightweight – perfect for wearable projects
• The Pulse Sensor is the most popular open-source heart rate sensor used by students, artists, athletes, makers, and developers worldwide! This tiny 16mm sensor can detect your heartbeat just by placing it on your fingertip or earlobe.
• Using optical technology (green LED + light-sensitive phototransistor), it measures the change in blood volume with each heartbeat – a technique called Photoplethysmography (PPG). The on-board amplifier and noise cancellation circuit give you a clean analog signal that can be directly read by any microcontroller.
• Just connect VCC to 3.3V or 5V, GND to ground, and Signal pin to any analog pin (A0) on your Arduino – upload the example code and watch your real-time heart rate in BPM on the Serial Monitor!
• Perfect for building fitness trackers, sleep monitors, emotion detectors, interactive art installations, or medical prototypes. Thousands of projects and tutorials are available online.
