Abstract
A sensor device configured to detect an occupancy condition in a space may comprise a thermally-insulated detector (e.g., a pyroelectric detector). The sensor device may comprise a heat-generating device, such as a light-emitting diode, that may be positioned within the enclosure at a location such that when illuminated, light from the light emitting diode illuminates a lens through the detector receives infrared energy. The printed circuit board may have a ground plane having at least a portion located between the detector and the light-emitting diode. The printed circuit board may comprise a slot extending from a front surface into the printed circuit board. The ground plane may comprise a gap surrounding slot. The slot and/or the gap in the ground plane may be located between the detector and the light-emitting diode to reduce the thermal transfer of heat generated by the light-emitting diode to the detector.
