Weather Forecast Pressure Kit with ESP32 + BMP280
ESP32 BLE Weather & Health Tag Kit: Monitor Pressure, Altitude & SpO2
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Assemble your own coin cell-powered beacon that continuously advertises live environmental pressure, altitude, temperature, and personal health metrics (SpO2 and heart rate) to any nearby phone—no pairing, no app. Whether you're tracking acclimatization on a Himalayan trek or building a wearable for a smart health dashboard, this intermediate kit delivers a practical, self-contained BLE peripheral you solder, program, and enclose yourself.
What You'll Build
A pocket-sized ABS-enclosed tag that reads BMP280 atmospheric data and MAX30102 optical biosensor readings, then broadcasts them as BLE advertising packets. Open any BLE scanner on your phone and the values appear instantly. The CR2032-powered design runs for days, making it ideal for continuous health monitoring, DIY weather stations, or altitude awareness during outdoor activities.
What You'll Learn
- Soldering surface-mount sensor breakouts onto a prototyping board and routing stable I2C connections.
- Programming the ESP32-C3 Super Mini to read BMP280 pressure/temperature and MAX30102 SpO2/heart rate, then format and broadcast data via BLE advertising.
- Understanding barometric pressure changes as a short-term weather predictor and accurate altitude estimator.
- Interpreting raw photoplethysmography signals and applying basic filtering for reliable SpO2 and pulse readings.
- Optimizing ESP32 deep-sleep and BLE advertising intervals for low-power battery operation.

Who This Kit Is For
This kit suits CBSE Class 12 students preparing physics investigations on environmental sensors, B.Tech ECE undergraduates demonstrating BLE communication protocols, participants in Smart India Hackathon 2024 building rapid health-IoT prototypes, and ATL Tinkering Lab coaches mentoring wearable electronics. If you can solder basic through-hole components and follow example code, you’ll end up with a real, battery-powered device—not just a breadboard experiment.
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 talk to our AI companion trained on this specific kit. It guides you through wiring, code upload, and troubleshooting. For personalised help, WhatsApp us directly—we reply fast.
Do I need a custom app to view the sensor data?
No. The tag broadcasts using standard BLE advertising. Any free BLE scanner app (like nRF Connect or LightBlue) on your phone instantly displays pressure, altitude, temperature, SpO2, and heart rate without pairing.
Can I change how often the data is sent to extend battery life?
Absolutely. The default firmware broadcasts every second, but you can modify the advertising interval and add ESP32 deep-sleep in code. The AI companion shows exactly where to adjust the timing.
Will this kit work correctly at high altitudes like Leh or Spiti?
The BMP280 is rated for operation up to 10,000 metres, and the MAX30102 functions on battery power. Our build guidance includes tips on cold-environment soldering and power stability to ensure reliable performance on high-altitude treks.
Weather — MAX30102 SpO2 and BMP280 altitude in a tiny BLE tag. Broadcasts health metrics continuously. No app needed.
