The document describes research conducted to understand how to reconnect neighbors, including surveys, interviews, and workshops. Key findings were that central "pioneer" individuals initiate connections, most neighbors want involvement but face logistical barriers, and neighbors are open to sharing information and using sensors. The researchers propose the GrassRoots sensor platform that allows creating sensor "recipes" to collect neighborhood data and connect individuals. Examples are given of how different community members might use GrassRoots sensors.
