Passive Sensor Passive Type Far Infrared Type PA-5312PA

A three-dimensional detection sensor ideal for detecting remaining occupants and ensuring safety in multi-story parking lots.

■Catching far-infrared energy emitted by humans The passive sensor (PA-5312PA) detects the difference between far-infrared energy emitted from objects such as walls and floors and that emitted from the human body with high sensitivity, outputting a signal. It is an ideal three-dimensional detection sensor for detecting residual individuals and ensuring safety in tower parking systems and similar applications. ■New fuzzy processing adopted For the first time in the world, fuzzy theory has been applied to passive sensors. The two outputs from the newly developed dual twin elements are processed by the CPU to separate the temperature difference and shape difference between the detected object and the background, allowing for accurate determination of whether the detected object is a human using fuzzy theory. It is hardly affected by phenomena that are likely to cause false triggers, such as small animals (like mice and cats), stray light, drafts, and external noise. ■High-density detection area Utilizing unique optical technology, a multi-parabola mirror has been adopted. This achieves an ideal detection area and allows for high-density detection in three-dimensional space. Additionally, it is compatible for installation on ceilings and walls.
