The CubeSat is built using an Arduino Nano, DHT22 for temperature and humidity, BMP180 for altitude, NEO-6M GPS for location, MPU6050 for orientation, and a 433 MHz RF module for wireless communication. A 18650 battery with a step-down module powers the system, and a patch antenna helps with signal transmission. First, a circuit diagram is made, and each component is tested separately before combining everything into a single program. A PCB is designed, manufactured, and assembled after testing the system for sensor accuracy and communication. Once complete, the CubeSat can track weather, altitude, and location while sending real-time data to a receiver. Future improvements may include longer-range communication and solar power. 🚀📡
- Calibrate Sensors – Ensure all sensors give correct readings.
- Send Data – Transmit real-time altitude, temperature, humidity, pressure, and location using the 433 MHz RF module.
- Track Weather & Altitude – Measure environmental conditions.
- Find Location – Update GPS coordinates in real-time.
- Communicate Wirelessly – Use a patch antenna for stable data transmission.
- Manage Power – Use the 18650 battery efficiently.
