Building upon the sucess of the Atlas flight computer used in flights 1 and 2, flight 3 will use the same Atlas flight computer coupled with a sensor daughter board connected via i2c.
This sensor board will have a number of features:
controlling the release of ballast from the tank
detecting the amount of ballast remaining
sensing internal temperature
sensing light intensity.
control the Morse beacon
