Abstract
The present invention provides apparatuses and systems for adjusting a communication channel between a control unit and a remote sensor. A system may include a control unit that controls an environmental unit and a remote sensor that provides data about an environmental factor as measured at the remote sensor. The remote sensor transmits a radio frequency (RF) signal that conveys the data to control unit through a directional antenna. The RF signal is received by the control unit through an omnidirectional antenna, and a signal strength parameter is determined from the received RF signal. A signal strength indication unit provides an indication from the signal strength parameter as a user adjusts the position of the directional antenna. With embodiments of the invention, a signal strength module generates an audio signal in accordance with an audio characteristic, which is indicative of the signal strength of the received RF signal.
