GP2Y0A21YK0F是夏普的一款距離測量感測器模組。它由PSD(position sensitive detector) 和IRED (infrared emitting diode) 以及信號處理電路三部分組成。由於採用了三角測量方法,被測物體的材質、環境溫度以及測量時間都不會影響感測器的測量精度。感測器輸出電壓值對應探測的距離。通過測量電壓值就可以得出所探測物體的距離,所以這款感測器可以用於距離測量、避障等場合。
Infrared proximity sensor made by Sharp. Part # GP2Y0A21YK has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.
