. Obtain 2 Arduinos, 1 Grove DHT11 sensor, 1 Grove BMP180 sensor, 1 Grove 315MHz RF link kit and 2 Grove shields
2. Connect DHT11 (Humidity and Temperature sensor) to pin A0, BMP180 (Barometer sensor) to pin I2C, 1 Grove 315 MHz receiver to the arduino connecting to the computer via the UART on the shield and 1 Grove 315 MHz transmitter to the arduino being sent up in the balloon via the UART on the shield.
3. Test the connection of the equipment to ensure that the data can be transmitted smoothly.
4. Mount the equipment on the inner surface of the housing.
5. Fill the balloon with helium until the balloon is about 1m in diameter.
6. Tie the balloon to the anchor hoop (Fig 1.1) and ensure that it is resting on top of the housing with minimal gaps (Fig 1.2)
7. Tie a string to the anchor hoop
8. Set the balloon into the air, anchoring it with the string so that it does not fly away and above 60m.
9. Retrieve the information that is pinged onto the computer (Temperature, Humidity and Pressure) (Fig 1.4)
10. Record findings of temperature, humidity and pressure on a graph.
11. After 12 hours (from 6am to 6pm), take the balloon down to prevent the equipment from getting damaged or the balloon from flying away.
