Patent ID: 7764171

Claim:
A system comprising: a control unit configured to control an environmental unit, the environmental unit affecting an environmental factor, the control unit including: a first antenna; a receiving module configured to receive a received radio frequency (RF) signal from a first remote sensor through the first antenna; a signal measurement module configured to determine a signal strength parameter, the signal strength parameter being indicative of a signal strength of the received RF signal; and a signal strength indication unit configured to provide an indication from the signal strength parameter; the first remote sensor positioned at a first location, the first remote sensor including: a second antenna; a transmitting module configured to convey a first datum in a first transmitted RF signal through the second antenna to the control unit about the environmental factor that is measured at the first location; and an adjustable component configured to alter a position of the second antenna; and the signal strength parameter being indicative of an optimum positioning of the second antenna.
