Drone Altimeter Kit with Arduino Uno & BMP280 — Apogee Detection Simulator

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit lets you build a working altimeter that simulates the critical apogee detection and ejection charge firing sequence used in model rocketry and drone payloads. The BMP280 sensor reads pressure changes, and when the Arduino detects a drop after apogee, it fires a relay — just like a real ejection system. You’ll understand how rockets sense their highest point and deploy recovery systems, all on a compact breadboard.

What You'll Build

A self-contained altimeter circuit on a 400-point breadboard that continuously monitors altitude via barometric pressure. At apogee, a red LED flashes and the relay closes briefly to mimic a parachute deployment signal. Test it by raising and lowering the sensor rapidly — the LED flashes at the highest point, proving the detection algorithm works.

What You'll Learn

• Read barometric pressure data with the BMP280 sensor over I2C
• Implement an apogee detection algorithm in Arduino code
• Control a relay module to simulate an ejection charge
• Use breadboard prototyping to build and test a real-world sensor system
