| 摘 要： | 设计了一种基于光电传感技术的物体检测系统,采用红外发光二极管和红外光电三极管的方式,进行传感电路设计。使用单片机NUC130LE3CN进行发光强度的控制与接收端电平的检测,发光强度由单片机IO口输出PWM波形进行控制。利用发光强度可调节这一特性,该方案可在不同环境光强下达到较高的检测灵敏度,同时还可提供报错功能。

| Abstract: | An object detection system based on optical sensing technology is designed using infrared light-emitting diodes and infrared phototransistor in the sensing circuit. The microcontroller NUC130LE3 CN is responsible for light emission intensity level control and the receiver detection,with luminous intensity controlled by the microcontroller IO port output PWM waveform. The adjustable luminous intensity offers high detection sensitivity in different ambient light intensities and error alert function. |
