This product is retired, please consider the new versionGrove - Light Sensor V1.2.
The Grove - Light sensormodule uses GL5528 photoresistor(light dependent resistor) to detect the intensity of light in the environment. The resistance of photoresistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light(i.e based on resistance value). The output signal from this module will be HIGH in bright light and LOW in the dark.
This module can be used to build a light controlled switch i.e switch off lights during day time and switch on lights during night time.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting StartedandIntroduction to Grove before your using of the product.

格羅夫光感應器模組使用 GL5528 光敏電阻 (光依賴電阻器) 來檢測環境中的光強度。當光強增加時, 光敏電阻的阻力減小。板上的雙放晶片 LM358 產生與光強相對應的電壓 (基於電阻值的 i. e)。該模組的輸出信號將在明亮的光線和黑暗的低。
本模組可用於建立一個光控開關, 在白天關閉電燈, 在夜間開關電燈。
對於所有的格羅夫使用者 (特別是初學者), 我們為您提供指導 PDF 文檔。請在使用該產品之前下載並閱讀序言-入門和樹林簡介。
