人体是一个特定波长的红外线发射体,检测到这种红外线的变化并予以放大处理,以推动适当的负载,是热释电人体红外线传感器及信号处理专用集成电路的功能。这种人体检测技术较之以往的超声波或微波方式更为灵敏与准确,它只对运动生物体敏感,对于非生物体或非运动生物体几乎不起作用,因而大大提高了动作的可靠性,在国外已经广泛应用于灯具控制、保安报警控制、自动门、自动风扇及自动门铃等等新产品之中。
The human body is a specific wavelength of infrared emitters, detect this change in the infrared and amplified to promote the appropriate load, pyroelectric infrared sensor and signal processing ASIC functions. This human detection technology is more sensitive and accurate than the previous ultrasound or microwave method. It is only sensitive to the moving organism and hardly affects the non-organism or the non-moving organism, thus greatly improving the reliability of the movement, In foreign countries have been widely used in lighting control, security alarm control, automatic doors, automatic fans and automatic doorbell and so on new products.
