Abstract: A remote control system for controlling operation of a fan assembly is provided. The system includes a first sensor module having a first housing, a first sensor, a first microprocessor, and a first RF transmitter. The first microprocessor is programmed to generate a first control signal to induce the first RF transmitter to transmit a first RF signal in response to a sensor signal from the first sensor. The first RF signal has a first address value and a first command value. The remote control system further includes a fan control module having a second housing, a second microprocessor, an AC power plug, an AC/DC voltage converter, a controllable switch, and an RF receiver. The RF receiver is configured to receive the first RF signal.

Abstract: The present invention provides methods, devices and systems for improving air quality. In one exemplary embodiment, the invention provides an air quality control system for maintaining or improving air quality within a room. The air quality control system includes a fan in fluid communication with a room. The fan is configured to vent air from within the room to control air quality therein. The air quality control system further includes a fluid flow sensor located proximate to a conduit. The fluid flow sensor is in communication with a wireless transmitter configured to generate a signal based upon fluid flow through the conduit. The air quality control system also includes a receiver configured to receive the wireless signal generated by the wireless transmitter, wherein the receiver is in communication with the fan to cause activation of the fan based upon the signal generated by the wireless transmitter.
