1. A control module comprising:
an enclosure having an enclosure opening at a first end;
a cover portion connected to the enclosure and covering the enclosure opening, the cover comprising an aperture in which a lens is located;
an antenna located within the cover portion;
a wireless communication circuit electrically coupled to the antenna for transmitting wireless signals at a transmission frequency;
a detector positioned to receive infrared energy through the lens of the cover portion, the detector comprising one or more pyroelectric elements that are responsive to the infrared energy and a housing having a front surface with a first opening through which the pyroelectric elements receive the infrared energy;
a control circuit electrically coupled to the wireless communication circuit and the detector, the control circuit configured to detect at least one of an occupancy condition or a vacancy condition in a space surrounding the control module in response to the infrared energy received through the first opening of the detector; and
a shield located over the front surface of the housing of the detector and electrically coupled to a circuit common of the control module, the shield having a second opening arranged overtop of the first opening of the housing, the second opening of the shield being sized to shield the pyroelectric elements from the wireless signals transmitted by the antenna in response to the wireless communication circuit.
