High altitude balloon project

.

For the playload we have used

• Raspberry pi
• Picam
• 3D Printer (for building an enclosure for the playload)
• BME280 temperature, pressure, and humidity sensor
• MPU-6050 Accelerometer and Gyroscope module
• NEO-6m GPS module

for tracking the playload we are using Automatic Packet Reporting System (APRS). It's always a good idea to have an alternative tracking methods, as a contingency plan. Hence, after lot of research we decided to use LoRa (Long-Range) module.

• Cheap
• LoRa modules are transceiver i.e, can be used as both transmitter or receiver
• With a clear SOV (Sight Of View) has a range >100km.
