This project provides a cellular and LoRa-based system that lets people rate the cleanliness of a restroom, and, in the case of negative feedback, send a notification to facilities management. Three buttons are wired to a Sparrow Reference Node, with each corresponding to a different experience rating: bad, ok, and good. These ratings are then sent to the Notecard and Notehub. From there, an operator can see when ok or bad ratings occur and dispatch someone to service the restroom.

By leveraging Sparrow and the Notecard, a large number of these monitors can be deployed in restrooms throughout a facility and send data to the cloud through a single Notecard-powered gateway.
