產(chǎn)品概述

GP2Y0A02YK0F是夏普的一款距離測量傳感器模塊。它由PSD(position sensitive detector) 和IRED (infrared emitting diode) 以及信號處理電路三部分組成。由于采用了三角測量方法，被測物體的材質(zhì)、環(huán)境溫度以及測量時間都不會影響傳感器的測量精度。傳感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，所以這款傳感器可以用于距離測量、避障等場合。

規(guī)格參數(shù)

  1. 距離測量范圍：20 to 150 cm
  2. 信號輸出類型：電壓模擬信號
  3. 包裝尺寸：29.5×13×21.6 mm
  4. 功耗： 標稱值33 mA
  5. 供電電壓：4.5 to 5.5 V
