光線傳感器 模擬傳感器互動(dòng)媒體

     Zui新推出的lightsensor是基于半導(dǎo)體的光電效應(yīng)原理所開發(fā)的光線傳感器，其可用來(lái)對(duì)周圍環(huán)境光的強(qiáng)度進(jìn)行檢測(cè)，結(jié)合各種單片機(jī)控制器可實(shí)現(xiàn)光的測(cè)量、光的控制和光電轉(zhuǎn)換等功能，此傳感器3p插針接口，可通過3p傳感器連接線（不分模擬與數(shù)字連接線）與傳感器擴(kuò)展板結(jié)合使用，可以制作光感相關(guān)的互動(dòng)作品。

what is a photocell?
photocells are sensors that allow you to detect light. they aresmall, inexpensive, low-power, easy to use and don't wear out. forthat reason they often appear in toys, gadgets and appliances.theys are are often referred to as cds cells (they are made ofcadmium-sulfide), light-dependent resistors (ldr), andphotoresistors.

photocells are basically a resistor thatchanges its resistive value (in ohms ω) depending on how much lightis shining onto the s face. they are very low cost, easy toget in many sizes and specifications, but are very innacurate. eachphotocell sensor will act a little differently than the other, evenif they are from the same batch. the variations can be reallylarge, 50% or higher! for this reason, they shouldn't be used totry to determine precise light levels in lux or millicandela.instead, you can expect to only be able to determine basic lightchanges

for most light-sentsitive applications like"is it light or dark out", "is there something in front of thesensor (that would block light)", "is there something interruptinga laser beam" (break-beam sensors), or "which of multiple sensorshas the most light hitting it", photocells can be a goodchoice!
