ABSTRACT:
A wireless sensor system for sensing a characteristic associated with a conveying system from which the sensor system generates operating power. The sensor system includes a transducer including an axle, a roller connected to the axle, and a link connected to the roller. The transducer may be configured to permit the roller to be positioned in contact with a conveyor belt of the conveying system so that the roller rotates about the axle or with the axle in response to translation of the conveyor belt. The sensor system also includes a power generator connected to the link, wherein the link transfers rotary motion from the roller to the generator, which generates power using the rotary motion input by the link. The sensor system further includes a sensor connected to the generator for receiving power, wherein the sensor is configured to sense the physical characteristic associated with the conveying system.
