Simulate Rocket Apogee Detection with the Greenhouse Pressure Monitor Kit and Arduino Uno

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

Ever wondered how model rockets know exactly when to deploy their parachute? This kit lets you build the logic behind that critical moment. Inside your own sealed greenhouse or container, the BMP280 barometric pressure sensor monitors pressure changes, and when a drop indicates peak “altitude,” the Arduino Uno commands a relay to fire a simulated ejection charge—three red LEDs flashing to signal the event. It’s a safe, table-top way to master rocketry telemetry before ever launching a real rocket.

What You'll Build

You’ll assemble a complete breadboard system with an Arduino Uno, a BMP280 sensor, and a 5V relay module. The circuit reads pressure values continuously, calculates when the simulation reaches apogee, and triggers the relay to illuminate the red LEDs. You’ll end up with a working pressure monitor that mimics how flight computers decide to eject parachutes—perfect for school science demonstrations or rocketry club challenges.

What You'll Learn

• Acquire precise pressure and altitude data from the BMP280 over I2C and convert it into real‑world decisions
• Program apogee‑detection algorithms in the Arduino IDE, identifying the exact moment pressure stops decreasing
• Control a high‑current relay safely using a transistor driver, with 1N4007 diodes protecting against voltage spikes
• Debug sensor data and timing logic with the serial monitor, just like professional rocketry avionics engineers do
