ESP32 Drone Altimeter Kit: Build a BLE Health Tag for Drones
ESP32 Drone Altimeter Kit: Build a BLE Health Tag for Continuous Drone Monitoring
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a tiny, battery-powered BLE tag that clips onto your drone and broadcasts live SpO2 and altitude readings. This isn't a display-on-phone project - it's a standalone wireless beacon that any nearby device can pick up, no pairing needed. Perfect for drone pilots who want to monitor altitude and pilot health without taking their eyes off the flight.
What You'll Build
A lightweight, self-contained BLE beacon that reads heart rate and blood oxygen via the MAX30102 sensor, measures barometric altitude with the BMP280, and advertises both metrics as standard BLE health data. Powered by an ESP32-C3 Super Mini and a coin cell, it fits in a matchbox-sized enclosure. Mount it on a racing drone, monitor pilot vitals, and log altitude excursions wirelessly.
What You'll Learn
- Interface I2C sensors (MAX30102 and BMP280) with an ESP32 microcontroller
- Program BLE advertising packets to broadcast health telemetry services without an app
- Optimise power consumption for coin-cell operation on a wearable/drone tag
- Assemble a compact soldered prototype on a PCB board and enclose it for flight mounting

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part works with 3.3V, I2C addresses clash | Pre-tested as a system, no address conflicts, ready firmware templates |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Ideal for CBSE plus-two students building electronics projects for board practicals, B.Tech ECE second-year students working on wearable health devices, and Smart India Hackathon teams needing a wireless telemetry prototype. ATL tinkerers who have moved beyond Arduino basics will love the BLE challenge.
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?
Open the AI companion via the QR code - it guides you step-by-step through soldering, wiring, and code. If you need a human, our WhatsApp team replies within hours.
Can I use this tag on a non-drone project, like a fitness band?
Absolutely. The BLE advertising of SpO2 and altitude works on any 3.3V battery setup; just change the enclosure. The skills translate directly to wearable health monitoring.
Do I need a smartphone app to read the data?
No. The tag advertises standard BLE service UUIDs - any BLE scanner app or nRF Connect will display SpO2 and altitude without custom software. You can also log data on a laptop with a BLE dongle.
What range can I expect from the BLE broadcast?
With the built-in chip antenna on the ESP32-C3 Super Mini, you'll get around 10-30 metres in open air, ideal for line-of-sight drone monitoring. Range can be extended with an external antenna but is not included.
Drone - MAX30102 SpO2 and BMP280 altitude in a tiny BLE tag. Broadcasts health metrics continuously. No app needed.
