Weather Forecast Pressure Kit v3
Weather Forecast Pressure Kit v3: LoRa-Based Rocket Telemetry System
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When you're launching a model rocket or a high-altitude balloon, telemetry tells you exactly what's happening inside the payload. This kit helps you build a fully functional system that captures pressure, altitude, orientation, and GPS location, then beams it down over LoRa to a ground station with a live, scrolling pressure chart.
What You'll Build
You'll assemble two Arduino Nano-powered units: a compact weather probe and a desktop ground station. The probe reads BMP280 pressure (used for altitude), MPU6050 tilt and acceleration, and NEO-6M GPS coordinates. All data streams at 10Hz over 433MHz LoRa. The ground station captures the packets, displays raw values on an OLED, and plots a scrolling chart of pressure altitude — a scaled-down version of the screen used by real rocket ground crews.
What You'll Learn
- Configure and pair two Arduino Nanos as transmitter and receiver over LoRa at 433MHz.
- Interface BMP280, MPU6050, and NEO-6M GPS modules simultaneously and poll them at high speed.
- Serialize sensor data into compact LoRa packets and implement error-checking for reliable transmission.
- Build a real-time visualization dashboard on dual OLEDs, including a moving chart that plots pressure-altitude in real time.

Who This Kit Is For
Advanced makers, engineering students, and aeromodelling enthusiasts interested in rocket telemetry or balloon experiments. Ideal for B.Tech ECE/EEE projects, Smart India Hackathon challenges, and IIT/NIT/VIT rocketry clubs. If you've ever wanted to track a high-altitude payload's pressure and position live from the ground, this kit gives you a fully replicable system.
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 QR code or message us on WhatsApp. It has been trained on the exact wiring, code, and common issues for this kit, so you'll get instant troubleshooting.
How far does the LoRa signal reach?
With the included 433MHz antennas and line-of-sight, you can expect 2–5 km in open air. Actual range depends on environment and antenna placement.
Can I modify the code to add more sensors?
Yes, both Arduino Nanos have spare analog and digital pins. The AI companion can guide you through adding extra modules like a humidity sensor or a magnetometer.
Is the kit suitable for a high-altitude balloon launch?
Absolutely. The BMP280 provides precise pressure-based altitude, the GPS tracks location, and the LoRa link sends all data to your ground station in real time. The waterproof enclosure and LiPo battery make it flight-ready.
Weather — RA-02 LoRa transmits BMP280 + MPU6050 + GPS at 10Hz to ground station OLED display with live chart.
