Abstract
Systems, devices, and methods for providing a sheet product dispenser with automated product level tracking functionality are provided herein. Various product level sensors are disclosed herein including a product level sensor configured to emit a signal toward an outer circumference of a sheet product roll on a spindle extending along a longitudinal axis and to receive a reflected signal. The product level sensor is positioned a radial distance away from the spindle and aimed to emit the signal in a direction that is not parallel and not perpendicular to the longitudinal axis. The product level sensor detects a parameter of the reflected signal corresponding to the distance between the product level sensor and the sheet product roll. Other example embodiments include mechanical product level sensors. Various communication protocols may be employed to limit transmission of data to conserve battery life while still maintaining desired communication functionality.
