Pulse Sensor Heart Rate Module for Arduino, ESP32 & Raspberry Pi

The Pulse Sensor Heart Rate Module is a compact biometric sensor designed to measure heart rate by detecting changes in blood flow using photoplethysmography (PPG) technology. It is widely used in Arduino and ESP32 projects for educational purposes, wearable electronics, fitness monitoring, and biomedical experiments.

Compatible with Arduino Uno, Nano, Mega, ESP32, Raspberry Pi (with ADC), ESP8266 NodeMCU, STM32, and other development boards, the module provides an analog output that can be processed to calculate heart rate in beats per minute (BPM).

Whether you're building a wearable health monitor, IoT fitness tracker, biomedical project, or educational electronics experiment, the Pulse Sensor offers an easy and reliable way to measure pulse signals.

Note: This module is intended for educational, research, and hobby electronics projects. It is not a medical device and should not be used for clinical diagnosis or treatment.

Frequently Asked Questions

Q. Is this compatible with Arduino Uno?

Yes. It is fully compatible with Arduino Uno, Nano, Mega, Leonardo, and other Arduino-compatible boards.

Q. Can I use it with ESP32?

Yes. It works with ESP32 analog input pins for pulse signal acquisition.

Q. Does it work with Raspberry Pi?

Yes. It can be used with Raspberry Pi when an external Analog-to-Digital Converter (ADC) is used, since Raspberry Pi does not include built-in analog inputs.

Q. How does the pulse sensor work?

The sensor uses photo plethysmography (PPG) to detect changes in blood flow caused by each heartbeat and outputs a corresponding analog signal.

Q. Is this a medical device?

No. This module is designed for educational, hobby, and research purposes and is not intended for medical diagnosis or clinical use.

Q. Where should the sensor be placed?

It is commonly placed on a fingertip or earlobe for pulse detection.

Q. Can I build a wearable heart rate monitor with this sensor?

Yes. It is commonly used in wearable electronics, IoT health monitoring projects, and fitness tracking prototypes.
