Radio Telemetry for Hobby Rockets

Hobby rocketry radio telemetry -- perhaps useful for assessing radio tower height requirements.


Above: Feather M0 LoRa with BMP180 pressure sensor, sending pressure data to a Mothbot, which is then received over serial port via python script and written to a file.

Four tosses are depicted. Noise is likely due to gusts of air over sensor intake.
