Pulse Sensor Heart Rate Sensor – Easy DIY Heart Rate Monitoring

Plug and Play Heart Rate Sensor for Arduino & Raspberry Pi

Looking for a simple way to add real-time heart rate monitoring to your next Arduino or Raspberry Pi project? The Pulse Sensor Heart Rate Sensor is designed for everyday makers and beginners, making it easy and affordable to track your pulse and heart rate at home, in the classroom, or on the go.

Key Features – Reliable Pulse Monitoring for Everyone

• Plug and play design – start measuring in minutes
• Compact and perfect for embedding in wearables
• Compatible with any microcontroller featuring an analog input (ADC)
• Works on both 3.3V and 5V systems
• Includes a well-supported, easy-to-use Arduino library

How the Pulse Sensor Heart Rate Sensor Works

This heart rate sensor uses an APDS-9008 ambient light sensor and a high-brightness green LED to sense your pulse. It detects small changes in reflected light as blood pulses through your fingertip or earlobe and outputs a clean, readable analog pulse signal. Pair it with Arduino, Raspberry Pi, or almost any other microcontroller for instant heart rate monitoring.
