Health Monitor Watch with SpO2 and BPM
Build a Health Monitor Watch with SpO2 & BPM — Arduino Nano Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine wearing a compact device on your wrist that continuously tracks your pulse rate and blood oxygen saturation, displaying real-time data on an OLED screen and alerting you with a buzzer when readings go outside safe limits. This advanced project combines wearable ergonomics with biomedical sensor integration, giving you the confidence to prototype health-tech solutions for hackathons, college projects, or personal wellness monitoring. You’ll learn to interface optical sensors, process biometric signals, and embed alerts—the same fundamentals used in clinical pulse oximeters.
What You'll Build
You’ll assemble a functional health monitor watch using an Arduino Nano and the MAX30102 optical sensor. The device reads SpO2 and BPM, displays them on a 0.96-inch OLED, and triggers an active buzzer if values exceed thresholds you set in code. The compact PCB layout, LiPo battery, and charging module make it a true wearable prototype. By the end, you’ll hold a custom health tracker that can be strapped to your wrist, ready for demo day or personal use.
What You'll Learn
- Calibrate the MAX30102 sensor for accurate SpO2 and heart rate readings
- Program an Arduino Nano to process real-time biometric data and drive an OLED display
- Implement conditional alert logic using a buzzer triggered by threshold values
- Design a compact wearable circuit layout and solder components on a prototype board for portability

Who This Kit Is For
This kit is ideal for B.Tech students in ECE, EEE, or Biomedical Engineering who need a wearable health project for semester submissions or hackathons like Smart India Hackathon. It’s also a strong fit for IIT/NIT/VIT/BITS project work, ATL Tinkering Labs targeting advanced health-tech prototypes, and dedicated hobbyists building a functional health monitor from scratch. No prior wearable experience is required, but you should be comfortable with Arduino coding and basic soldering.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to access the AI companion that walks you through every connection and code line. For personalised help, our team is also available on WhatsApp.
Is the MAX30102 sensor accurate enough for medical use?
The MAX30102 is robust for prototyping and personal wellness. It delivers reliable readings after calibration as shown in our guide, though it is not certified for clinical diagnosis.
Can I upload the code to the Arduino Nano using a standard USB cable?
Yes, the Nano has a built-in USB interface. Connect it to your computer, install the MAX30102 and OLED libraries, and use the Arduino IDE to upload the sketch our AI companion provides.
How do I power the watch and make it portable?
The kit includes a 3.7V 400mAh LiPo battery and a TP4056 charging module. Solder the battery via the module to power the board; recharge using any micro‑USB cable. A full charge lasts several hours of continuous monitoring.
MAX30102 reads pulse rate and blood oxygen saturation. OLED shows BPM and SpO2. Buzzer on abnormal values.
