    • Provided according to one embodiment is a thermostat having a housing including a forward-facing surface comprising a passive infrared (PIR) motion sensor disposed inside the housing for sensing occupancy in the vicinity of the thermostat. The PIR motion sensor has a radiation receiving surface that detects the lateral movement of an occupant in front of the forward-facing surface. A grille member having one or more openings is also included along the forward-facing surface and placed over the radiation receiving surface of the PIR motion sensor. The grille member is dimensioned to visually conceal and protect the PIR motion sensor disposed inside the housing promoting a visually pleasing quality of the thermostat, while also permitting the PIR motion sensor to effectively detect the lateral movement of the occupant. In one embodiment, the grille member openings are slit-like openings oriented along a substantially horizontal direction.
    • 根据一个实施例提供的是具有壳体的恒温器,壳体包括前向表面,其包括设置在壳体内部的被动红外(PIR)运动传感器,用于感测恒温器附近的占用。 PIR运动传感器具有辐射接收表面,其检测乘员在前向表面前方的横向移动。 具有一个或多个开口的格栅构件也沿着前向表面包括并放置在PIR运动传感器的辐射接收表面上。 格栅构件的尺寸设计成可视地隐藏和保护设置在壳体内的PIR运动传感器,促进恒温器视觉上令人满意的质量,同时还允许PIR运动传感器有效地检测乘员的横向运动。 在一个实施例中,格栅构件开口是沿着基本上水平的方向定向的狭缝状开口。
