Pulse Rate Monitoring System and ECG Measurement System.

Pulse rate monitoring system and ECG measurement system.
Firstly, I’m going to present my project — a Pulse Rate Monitoring System using Arduino Uno and a Pulse Sensor.

**The purpose of this project is to measure a person's heart rate in real-time using a simple and low-cost electronic setup.

**Let me start with the components I used:**

* An **Arduino Uno** microcontroller
* A **Pulse Sensor** (usually placed on the fingertip or earlobe)
* Some jumper wires and a **breadboard**
* And a **USB cable** to connect the Arduino to a computer

**Here’s how it works:**
The **pulse sensor** detects the change in blood volume through the fingertip with every heartbeat. It sends analog signals to the Arduino. The Arduino then processes these signals to calculate the number of heartbeats per minute, commonly called BPM — Beats Per Minute.

**Now, let’s talk about the working process:**

* The pulse sensor is connected to analog pin A0 on the Arduino.
* I’ve uploaded a simple program using the Arduino IDE.
* The Arduino reads the analog data from the pulse sensor.
* It filters the signal and counts the peaks, which represent heartbeats.
* Finally, it calculates the BPM and prints it on the **Serial Monitor**.

**To demonstrate,** when I place my finger on the sensor, the LED on the pulse sensor starts blinking with each heartbeat. In a few seconds, the serial monitor shows my heart rate, for example, 72 BPM.

**This project is useful in many areas** — like fitness devices, basic health check-ups, or even stress monitoring. It also helps students learn about biosignals and electronics together.
Now, I’m going to present my project — an ECG Measurement System using Arduino Uno, an ECG Sensor Module, and 3 Electrodes.**

**ECG** stands for **Electrocardiogram**. It is a method to record the electrical activity of the heart. With this project, we can visually monitor the heart’s rhythm and detect abnormalities in heartbeat patterns.

**Let’s start with the components I used:**

* An **Arduino Uno**
* An **ECG sensor module** — like the AD8232
* **Three electrodes**
* **Connecting wires**
* A **USB cable**
* And a **computer with Arduino IDE and serial plotter**

**Here’s how it works:**
The **electrodes** are attached to the body — usually one on the right arm, one on the left arm or leg, and the third as ground. These pick up the tiny electrical signals produced by the heart.

These signals are very weak, so the **ECG sensor module** amplifies and filters them. It then sends the processed signal to the Arduino through analog pin A0.

**The Arduino reads this analog signal**, and when we open the **Serial Plotter** in the Arduino IDE, we can see the ECG waveform — those familiar P, QRS, and T waves — in real time.

**Now the connection setup:**

* ECG module OUT goes to **A0**
* GND and 3.3V or 5V go to Arduino GND and 3.3V/5V
* Electrodes connect to the sensor's RA, LA, and RL pins

**To demonstrate:** when I connect the electrodes to the body, and run the Arduino code, the **Serial Plotter** shows the ECG waveform moving in real-time — this is the electrical activity of my heart.

**This project is useful for learning about human physiology, electronics, and biomedical signal processing.** It shows how we can use simple tools to understand complex biological processes.
