Greenhouse Pressure Monitor Kit v3
Greenhouse Pressure Monitor Kit v3 — 10Hz LoRa Telemetry for High-Altitude Rocket & Balloon Payloads
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Whether you're prototyping a sounding rocket avionics bay or a high-altitude balloon payload, live pressure, attitude, and GPS data streaming to a ground station is non-negotiable. This kit equips you with a dual-Arduino LoRa mesh that captures BMP280 barometric pressure, MPU6050 6-axis motion, and NEO-6M GPS coordinates at a steady 10Hz refresh, then transmits wirelessly to an OLED dashboard with a live chart — exactly the kind of real-time monitoring used in space simulation and rocketry testing.
What You'll Build
A portable, waterproof wireless sensor node that transmits environmental data over 433MHz LoRa to a battery-powered ground station. The ground station plots pressure vs. time on a live scrolling graph, displays altitude and orientation, and logs GPS coordinates — all from a self-contained system that fits in a rocket payload bay or under a balloon's payload string.
What You'll Learn
- Implement LoRa peer-to-peer communication with error checking for noisy RF environments
- Fuse BMP280 pressure/altitude data with MPU6050 accelerometer and gyro for attitude-compensated atmospheric profiling
- Parse NMEA sentences from a GPS module and synchronize with sensor data at a fixed 10Hz loop rate
- Design and assemble a rugged, battery-powered sensor node with PCB prototyping and soldering

Who This Kit Is For
Advanced-level builders — B.Tech ECE/EEE final-year students working on rocketry or UAV telemetry projects, Space & Rocketry club members at IIT, NIT, VIT, BITS campuses, aerospace enthusiasts participating in Smart India Hackathon challenges, and professionals prototyping high-altitude sensing payloads. If you've already worked with Arduino and want to move from wired sensors to long-range wireless data links, this kit bridges that gap.
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 inside the box to open the AI companion, trained on this exact kit. You can also message us on WhatsApp for hands-on support from a builder who's built this same project. Response within 2 hours during business hours.
Does this kit include everything for both transmitter and receiver?
Yes — two Arduino Nanos, two LoRa modules, two OLEDs, two antennas. You'll build the sensor node (with BMP280, MPU6050, GPS) and the ground station receiver with its own OLED display and live chart.
What is the maximum range of the LoRa link?
With the included 433MHz antennas and line-of-sight, expect 1-2 km. Range can be extended to 5+ km with aftermarket high-gain antennas and careful placement — ideal for high-altitude balloon flights.
Is the enclosure really waterproof for rocket or balloon use?
The included IP65-rated enclosure protects against rain and condensation, but is not submersible. You'll seal cable entries with silicone sealant (not included) to maintain integrity during flight.
Greenhouse — RA-02 LoRa transmits BMP280 + MPU6050 + GPS at 10Hz to ground station OLED display with live chart.
