SENSOR HUB COMPRISING A ROTATION ENCODER
First Claim
1. An apparatus comprising:
- a rotation sensor configured to receive power from a controller of a monitored machine;
a wireless communication module; and
a processing device, operatively connected to the rotation sensor and the wireless communication module, configured to receive the power from the controller of the monitored machine and to receive rotation sensor data from the rotation sensor and send speed or position data or both, based on the rotation sensor data, to an external processing device via the wireless communication module.

Abstract
A sensor hub for use in machine condition monitoring comprising a rotation sensor and a wireless communication module each operatively connected to a processing device. The rotation sensor and processing device are configured to receive power from a controller of the monitored machine. One or more additional sensors, which may be associated with the monitored machine or another machine, may also be operatively connected to the processing device. In an embodiment, the additional sensors may comprise any one or more of, or any combination of, an accelerometer, a temperature sensor, an acoustic sensor, an high frequency sensor, an humidity sensor, a barometric pressure sensor, a current sensor or a proximity sensor. The wireless communication module may support an ad hoc wireless communication protocol. Further, the wireless communication module may receive additional sensor data from one or more wireless sensor nodes associated with the monitored machine or another machine.
