An apparatus configured to sense presence and motion in a monitored space is presented. The apparatus includes a dual-element assembly with a first thermal sensing element and a second thermal sensing element configured to produce a direct current output that is sustained at a level substantially proportional to an amount of thermal energy being received at the thermal sensing elements. A lens array (or equivalent optics) is coupled to the elements, having a plurality of lenses directing incident thermal energy from a plurality of optically-defined spatial zones onto the sensing elements. An electronic circuitry is configured to read a resulting signal of the dual-element assembly and an individual output signal of each the first thermal sensing element and the second thermal sensing element. 提出了种配置为感测监控空间中的存在和运动的装置。装置包括双元件组件，双元件组件具有配置为产生直流输出的第热感测元件和第二热感测元件，该直流输出维持在与在热感测元件处接收的热能的量大致成比例的水平。透镜阵列(或等效的光学器件)耦合到所述元件、具有多个透镜，所述多个透镜将来自多个光学限定的空间区域的入射热能导引到感测元件上。电子电路配置为读取双元件组件所得到的信号以及第热感测元件和第二热感测元件中的每个的单独输出信号。
