如何用光电二极管测量光的电压？

光没有电压。所以无法衡量。
但是你可以用光电二极管来检测光的存在和最亮。如果这是一个研究项目。从谷歌开始应该很容易。
这里是一个你可以开始

但又一次。不确定这是否是你的项目所需要的，因为它似乎在不断变化。
最好是在这里发布项目的要求或规范。
正如我之前提到的，当你一次发布一点信息时，它是无济于事的，没有人在没有真正理解你的要求的情况下是无能为力的。
一切都取决于你。



     以下为原文
  Light doesn't have a voltage. So can't be measured.
    But you can detect the existance and brightest of light using photodiode. And if this is a research project. it should be easy to start with GOOGLE.
    here is one that you can start with
    http://physlab.lums.edu.pk/images/1/10/Photodiode_circuit.pdf
    But again. Not sure if that is what's required for your project, as it seems to keep on changing.
    The best is to post the requirement or specification of project here.
    As I mentioned before, it won't help as you are giving out information one bit at a time and no people here can't help without actually understanding your requirment.
    It's all up to you.

光子确实有电子伏特测量的能量，我想这不是你想要测量的。



     以下为原文
   Photon does have energy measured in electron volt, I think this is not what you want to measure.

HL：我测量了下面的一些读数……请看一下。我使用红色LED并测量其频率在不同的距离。
距离（cm）f（kHz）
零点五四一八
1 245
一点五一二五
2 73
二点五一八
无光10
因为你知道我使用TSL255，其输出频率范围为250（+- 50）kHz，为670nm。我认为我得到了正确的价值观。你有什么建议？
如果它是正确的，你可以帮助我，为什么测量光频率是更好的方法在PSoC然后与任何其他传统的微控制器。



     以下为原文
  HL: i have measure some reading below...plz have a look at it. i've used red led and measure its frequency at different distances
    Distance(cm)       F(kHz)
    0.5                             418
    1                                 245
    1.5                              125
    2                                 73
    2.5                              18
    no light                       10
     
    since u know that i m using tsl235 whose output frequency range is aroun 250 (+- 50) kHz for 670nm. and i think i m getting correct values. what do u suggest.
    and if its correct can u plz help me out why measuring light frequency is better approach in psoc then with any other conventional microcontroller.

你的暗偏移是10kHz。
让我们来控制
@ 1cm你得到245 - 10＝355kHz。在距离2cm的地方，我们期望这个值的四分之一。
＝235/4＋10＝68.75，这已经相当于你测量的73。这些差异可能来自LED收集器LSENS。

     以下为原文
  Your dark-offset is 10kHz.
    so let's control
    @1cm you get 245 - 10 = 235kHz. at a distance of 2cm we expect a quarter of that value
    = 235 / 4 + 10 = 68.75 which is already quite near to your measured 73. These differences may come from the LED-collector-lense.

鲍伯：你认为这些价值观是正确的吗？你能帮助我为什么用PSoC测量光的方法比其他传统的微控制器更好



     以下为原文
   Bob: what u suggest these values are correct?  and can u help me why my approach of measuring light with psoc is better then nay other conventional microcontroller

暗偏移是lt＝10赫兹，而不是kHz。
问候，Dana。



     以下为原文
  The dark offset is <=10 Hz, not Khz.
     
    Regards, Dana.

达纳雅小于10赫兹



     以下为原文
   Dana ya its less than 10 Hz

DAna：它是10千赫。
当我在AN228上工作的时候，我需要再问一件事。并进行硬件连接。它在液晶显示器上的显示不会改变
其显示
欠量程
FFFFF
你能告诉我为什么吗？？



     以下为原文
   DAna: its 10 kHz.
    i need to ask one more thing dana when i m working on AN2283. and doing its hardware connection. its display on lcd is not changing
    its showing
    underrange
    fffff  0000f
    can u tell me why so.??

我很困惑。电压读数为赫兹？



     以下为原文
   I am confused. voltage reading in HZ?

传感器将光电平转换为频率。
邮政项目在这里和论坛，将看看它。
问候，Dana。



     以下为原文
  Sensor converts light level to frequency.
     
    Post you project here and forum, will take a look at it.
     
    Regards, Dana.

从数据的角度看，它看起来像是在测量光源和传感器之间的距离。但不确定这到底是什么。我希望我们不会把Ishu带入错误的方向。如果这是一个项目，那么浪费时间走错了路。



     以下为原文
   By the look of the data, it looks like it is measuring the distance between the light source and the sensor. But not sure if that is the what it actually is. I hope we are not leading Ishu to a wrong direction. And if it is a project, then wasting time in the wrong path.
