This document provides a weekly progress report from the Instinct design group (ID) engineering team. The team members are working on a food waste detection project and their product is called P' Jub. This week they discussed food waste and divided work. They are using a sensor to detect food waste levels between 0-10,000ppm. Next week the team will assign work for each member to continue developing the project.
