Pulse Meter using Arduino Nano | DIY Heart Rate Monitor
Monitoring heart rate is a fascinating intersection of health and technology. In this blog, we’ll guide you through building a pulse meter using an Arduino Nano and a pulse sensor module. This simple project is perfect for beginners exploring wearable tech, DIY health monitoring, or just learning how sensors work!
Understanding the Pulse Sensor
The pulse sensor is a lightweight, easy-to-use module that measures heart rate by detecting changes in blood flow from a fingertip or earlobe. These changes are converted into electrical signals, which are processed by the Arduino Nano to calculate beats per minute (BPM).
Key Features of the Pulse Sensor:
- Compact and lightweight for DIY wearable projects.
- Outputs analog signals based on heartbeat detection.
- Easy integration with microcontrollers like Arduino.
Components Needed
To build your pulse meter, you’ll need the following components:
- Arduino Nano
- Pulse Sensor Module
- OLED Display (optional) for visualizing heart rate readings
- Jumper Wires
- Breadboard (optional)
Wiring the Components
Connections:
-
Pulse Sensor:
- VCC → 5V (Arduino Nano)
- GND → GND (Arduino Nano)
- Signal → A0 (Analog pin on Arduino Nano)
-
OLED Display (optional):
- VCC → 5V
- GND → GND
- SDA → A4
- SCL → A5

How It Works
-
Heartbeat Detection:
The pulse sensor detects variations in blood flow as you place your fingertip on it. These variations correspond to your heartbeats. -
Processing:
The Arduino Nano reads the sensor’s analog output and determines if it exceeds the predefined threshold. If a heartbeat is detected, it calculates the time difference between beats to compute the BPM. -
Display:
The calculated BPM is displayed on an OLED screen (if connected) or output via the serial monitor.
Applications
- Wearable Health Tech: Integrate this setup into a wristband or smartwatch for continuous heart rate monitoring.
- Fitness Projects: Track your heart rate during workouts or yoga sessions.
- Learning Platform: A great project to understand sensors, signal processing, and DIY electronics.
