Classroom CO2 Monitor Kit with Arduino Nano + BMP280 — Real-Time Environmental CanSat Payload

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

Assemble a fully functional CanSat that measures CO2, ozone, UV, temperature, pressure, humidity, and GPS location, then transmits the data in real-time over LoRa to a ground station. Originally conceived for school ventilation audits, this payload is built to fly — launch it inside a model rocket, high-altitude balloon, or use it as a stationary air quality monitor. Every component is pre-soldered and tested for flight-ready reliability.

What You'll Build

You'll construct a multi-sensor payload that logs environmental and positional data, streams it via 433MHz LoRa, and displays it on a receiver computer. The entire system fits inside a foam enclosure that can be secured inside a standard CanSat canister or balloon payload bay. When deployed, it gives you real-time insight into CO2 levels, UV exposure, and GPS location — a complete telemetry chain in one kit.

What You'll Learn

• Integrating multiple I2C and SPI sensors (BMP280, MH-Z19B, ML8511, DHT22) with Arduino Nano on a single bus
• Implementing long-range LoRa communication using RA-02 modules and 433MHz antennas for reliable telemetry
• Parsing NMEA sentences from the NEO-6M GPS and synchronizing all sensor readings with the DS3231 RTC for precise timestamps
• Designing a compact power supply with a LiPo battery, TP4056 charger, and decoupling capacitors for stable flight operation

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This advanced payload targets final-year B.Tech ECE and EEE students building aerospace projects, Smart India Hackathon teams developing real-time environmental telemetry setups, and CanSat competition squads from IITs, NITs, VIT, BITS, and other Indian universities. It is equally valuable for researchers prototyping low-cost air quality networks for Indian schools, enabling long-term CO2 and ventilation monitoring from a single coherent kit.
