PPG Wrist Pulse Sensor Module

The PPG Wrist Pulse Sensor Module is a compact photoplethysmography (PPG) sensor designed for wrist, arm, or finger pulse measurement, delivering a continuous analog pulse waveform and a selectable square-wave heart-rate output compatible with common microcontroller platforms. The module operates from a 5V supply, consumes under 10mA in typical use, and exposes an XH2.54-4P interface for direct connection to Arduino and STM32 development boards, enabling straightforward integration into wearable and prototype projects.

Features

Uses green-light PPG (PhotoPlethysmoGraphy) for stable pulse signal acquisition.
Dual output modes: continuous analog pulse waveform and digital square-wave pulse output.
Compatible with 5V systems and communicates via an XH2.54-4P connector for easy hookup.
Low current consumption (<10mA) for battery-powered and wearable applications.
Library and example code available (Arduino library “CheezPPG”) with 125Hz sampling and serial output for raw, filtered, peak, HR, and HRV data.

Notes:

This is a static detection sensor. Do not move it randomly or press it too tightly during measurement.
This product is not a professional medical device and cannot be used as an auxiliary accessory for diagnosis and treatment.

        The baud rate is 115200
        Sampling rate: 125Hz 

Serial output content (ASCII):
        Raw data, smooth filter data, band pass filter data, heartbeat detection data, heart rate data, HRV (SDNN) data

#include "CheezPPG.h"
 
#define INPUT_PIN A0    // PPG Pin
#define SAMPLE_RATE 125

CheezPPG ppg(INPUT_PIN, SAMPLE_RATE);  

void setup() 
{
  Serial.begin(115200); 
  ppg.setWearThreshold(80); // Set the wearing threshold. If wearing detection is not required, it can be set to -1
}

void loop()

    Serial.println(

      String((int)ppg.getAvgPPG())    + "," +  // Smooth filter data
