A control device for a ceiling fan may have a motor drive circuit configured to control a rotational speed of a motor of the ceiling fan, an occupancy sensing circuit, and a control circuit configured to adjust the rotational speed of the motor in response to a detected occupancy or vacancy condition. The control circuit may process the signals generated by the occupancy sensing circuit to eliminate the effects of vibrations and/or wobbling of the ceiling fan. The control circuit may control the motor drive circuit to adjust the rotational speed of the motor in response to an accelerometer to minimize the magnitude of the wobble of the ceiling fan. The control circuit may be configured to learn a preferred rotational speed for the motor. The control circuit may also be configured to control the rotational speed of the motor to affect a thermal comfort level of an occupant.

A grow system. The system includes growing plants in grow modules that are individually moveable. The plants grow in trays where roots never touch the water supply. The plumbing to the grow modules is a low flow, one way flow continual drip system that is hands free. A mobile robot can navigate around a growspace, bring any grow module from one location to another, and perform growspace operations. The growspace is a control space with data source zones and a control space manager. The control space manager can collect data and control different variables across different data source zones in order to determine optimal policies and conditions for data source growth and generation.

The present invention is a fan having rotation sensing, comprising a casing, a motor disposed within the casing, a rotation sensing unit, and a control unit, the rotation sensing unit detecting a first rotation of the casing and outputting a first sensing signal, the control unit having a controller electrically coupled to the rotation sensing unit and the motor, the controller receiving the first sensing signal according thereto to control the motor to perform a first operation mode. Through this design, an operation mode of the fan can be adjusted according to the rotation of the fan in the present invention.

A control space operating system. The system includes a control space with one or more data source zones and a control space manager. The control space manager can collect data and control different variables across different data source zones in order to determine optimal policies and conditions for data source growth and generation.

A growspace automation system and method. The system includes a grow space with localization structures and a mobile robot. The mobile robot comprises sensors, a mobility mechanism, and a plurality of mobility modules. The mobile robot is configured to automate growspace processes, such as transport, watering, sensing, or cleaning.

A plumbing system and water transport method. The system includes a global water source, a one way water transport mechanism, a growing tray, and a local buffer. The local buffer separates the global water source and the growing tray to prevent cross-contamination of water. The local buffer also continuously provides water to the growing tray on demand without the need for filtering or dumping of used or excess water. This results in low flow, efficient water transport.
