This week Team MATR has been hard at work to meet the goals set for the second Qualitative Review Board of the semester (QRB2). The presentation for QRB2 will be delivered to IPPD faculty on Tuesday, February 22. The Electrical and Computer Engineers have continued work on system integration, writing programs for communication between the microcontroller and the peripheral sensors. Testing has been done on the ambient light sensor, pressure and temperature sensors. The PCB design for the full electrical system is still in its early stages, and will continue to take shape as the remaining sensors are tested and the GPS and ARGOS modules are integrated. On the Mechanical Engineering side of the project, the 2-piece epoxy enclosure has been sealed in preparation for waterproof testing, which will be conducted in time to report on the results at QRB2. Beyond waterproof testing, a new design for the shape of the enclosure is in development as the electrical system evolves through the system integration process.
