GraftSense sensor module kit

GraftSense is a modular hardware kit of sensor modules, expansion boards and learning resources for STEM teaching and rapid prototyping. Modules share a Grove-style connector, so students and engineers can plug sensors into a controller board and get a working demo quickly. The team ships individual modules, 20–30 module kits, course materials and documentation.
