Complete Payload Integration


Lead Author: Hanayo Shelton

Goals for payload integration:
The goal of the complete payload integration is ensure that all instruments will be put together as one complete payload which will travel up to near 30km above the ground and recovered successfully in two hours after the launch of the balloon.

Payload integration:
All sensors such as a humidity sensor, an accelerometer, and a thermometer as well as a data logger were integrated into one circuit on a perf-board, and put inside a sturdy Styrofoam box (16 in ×18in). A camera which will be used to take pictures over the flight was mounted on one side of the box with the lens exposed to the outside. A video camera was mounted on the outside of the box to record video images during the flight. GPS-transmitter was placed inside the box with an antenna penetrated through the box wall to send the information of the location of the balloon. Parachute was attached to the outside of the box by 4 strings connected to the corners of the box to secure a safe landing of the payloads. Our payloads weighed about 2.5kg.



Recomendations on integaration:

The total weight of our payloads was a little over 2kg which was a desirable weight for our project. We would be able to decrease the weight by making the size of the box smaller.
