13怎样用霍尔电流传感器ss49e输出电压来计算被测电流的大小
怎样用霍尔电流传感器ss49e输出电压来计算被测电流的大小1. AT90S8515介绍AT90S8515是一种基于精简RISC指令集的嵌入式单片机，它有8K的可下载的FLASH存储空间，512字节的EEPROM，512字节的SRAM。
它还带有看门狗定时器，2个中断源，2个定时器/计数器。
2. 里程测量传感器模块设计方案一、使用光敏电阻对里程进行测量。
将光敏电阻安装在自行车前叉的一侧，在同等高度的另一侧安上一个高亮度的发光二极管。
在同等高度的辐条上贴上一圈黑色材料，并在黑色材料上打上等间距的小孔，这样当小孔经过光敏电阻时，光敏电阻根据光电流的变化发出脉冲，从而测量里程。
方案二、利用编码器对车轮的圈数进行测量。
将旋转编码器安装在车轴上，这样每当车轮转过一定的距离编码器就会发出一个脉冲。
利用脉冲数对里程进行测量。
方案三、利用霍尔元件对里程进行测量。
将霍尔元件安装在车前叉的一侧，在车圈侧面等间隔贴多个磁片。
当磁片经过霍尔元件时，霍尔元件输出端的电压发生变化产生脉冲，单片机根据脉冲数来计算里程。
光敏电阻对光特别敏感，当白天行驶时，外界光源将导致光敏电阻发出错误信号；光敏电阻对环境的要求相当高，如果光敏电阻或发光二极管被泥沙或灰尘所覆盖，光敏电阻就不能再进行测量；在雾天和雨天光敏电阻的测量的效果也不好。
而编码器必须安装在车轴上，这样安装就会给用户带来很多不便。
霍尔元件不受天气的影响，即便被泥沙或灰尘覆盖对测量也不会有任何影响。
由霍尔元件加整形电路构成的霍尔开关系统，具有输出响应快，数字脉冲性能好，安装方便，性能可靠，不受光线、泥水等因素影响，价格便宜的优点。
所以本设计采用方案三。
3. 显示系统设计方案一、用数码管显示信息。
利用6个数码管显示数字信息，并用8个发光二极管分别指示显示量的内容和单位。
例如数码管显示10.00,并且指示速度的发光二极管亮，它表示当前的平均速度为10.00千米／小时。
方案二、用液晶显示器显示信息。

SS490系列线性霍尔效应传感器芯片说明书
SS490SERIESLinear Hall-effect Sensor ICsDESCRIPTIONThe SS490 Series are small, versatile, linear Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The integrated circuitry provides increased temperature stability and sensitivity. Laser-trimmed, thin film resistors provide high accuracy (null to ±%, sensitivity up to ±3%) and temperature compensation.They respond to either positive or negative Gauss, monitoring either or both magnetic poles. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. The positive temperature coefficient of the sensitivity (+0.02%/°C typical) helps compensate for the negative temperature coefficients of low-cost magnets, providing a robust design over a wide temperature range. Rail-to-rail operation (over full voltage range) provides a more usable signal for higher accuracy. These products have an operating temperature range of -40°C to 150°C [-40°F to 302°F], appropriate for industrial and automotive environments.PORTFOLIOHoneywell offers a variety of linear Hall-effect sensor ICsfor potential use in many applications.

All specifications subject to change without notice. Nektar is a trademark of Nektar Technolog y, Inc.Nektar SE493IntroductionThank you for buying our SE49 controller keyboard from Nektar Technology.The SE49 controller comes with setup software for many of the most popular DAWs. This means that for supported DAWs, the setup work has largely been done and you can focus on expanding your creative horizon with your new controller. The Nektar DAW Integration adds functionality that makes the user experience more transparent when you combine the power of your computer with Nektar SE49.You also get a full version of Bitwig 8-Track software which of course feature SE49 integration.In addition, the SE49 range allow for complete user configurable MIDI control so if you prefer to create your own setups, you can do that too.We hope you will enjoy playing, using and being creative with SE49 as much as we have enjoyed creating it.Box ContentYour SE49 box contains the following items:∙The SE49 Controller keyboard ∙Printed Guide ∙A standard USB cable ∙Software license card If any of the items above are missing, please let us know via email: ***************************SE49 FeaturesMinimum System RequirementsAs a USB class compliant device, SE49 can be used from Windows XP or higher and any version of Mac OS X.The DAW integration files can be installed on Windows Vista/7/8/10 or higher and Mac OS X 10.7 or higher.∙ 49-note full-sized velocity sensitive keybed ∙ 1 MIDI assignable fader ∙ Octave up/down buttons with LED indicators ∙ Transpose up/down buttons assignable to other functions ∙ Octave and Transpose buttons can be switched to control transport on your DAW ∙ USB port (back) and USB bus powered ∙ Power on/off switch (back) ∙ 1/4” jack Foot Switch socket (Back) ∙ Nektar DAW Integration ∙ Bitwig 8-Track licenseGetting StartedConnection and PowerThe SE49 is USB Class compliant. This means there is no driver to install to get the keyboard set up with your computer.SE49 uses the built-in USB MIDI driver which is already part of your operating system on Windows andOS X as well as iOS (via the optional camera connection kit).This makes the first steps simple:∙ Locate the included USB cable and plug one end in to your computer and the other in to your SE49∙ If you want to connect a foot switch to control sustain, plug it in to the 1/4” jack socket on the back of the keyboard∙ Set the power switch on the back of the unit to OnYour computer will now spend a few moments identifying the SE49 and subsequently you will be able to set it up for your DAW.Nektar DAW IntegrationIf your DAW is supported with Nektar DAW integration software, you’ll need to first create a user account on our website and subsequently register your product to then gain access to the downloadable files applicable to your product.Start by creating a Nektar user account here: /registrationNext follow the instructions given to register your product and finally click on the “My Downloads” link to access your files. IMPORTANT: Make sure to read the installation instructions in the PDF guide, included in the downloaded package, to ensure you don’t miss an important step.Using SE49 as a Generic USB MIDI ControllerYou do not need to register your SE49 in order to use your controller as a generic USB MIDI controller. It will work asa USB class device on OS X, Windows, iOS and Linux.However there are several additional benefits to registering your product:∙ Notification of new updates to your SE49 DAW integration∙ PDF download of this manual as well as the latest DAW integration files∙ Access to our email technical support∙ Warranty service4Keyboard, Octave, Transpose & ControlsThe SE49 features a 49 note keyboard. Each key is velocity sensitive so you can play expressively with the instrument. There are 4 different velocity curves for the keyboard so you can chose a less or more dynamic curve to suit your playing style. In addition, there are 3 fSE49ed velocity settings.We recommend you spend a little time playing with the default velocity curve and then determine if you need more or less sensitivity. You can learn more about velocity curves and how to select them in the “Setup” section.To the left of the keyboard you find the Octave buttons.∙ With each press, the left Octave button will shift the keyboard down one octave.∙ The right Octave button will similarly shift the keyboard up 1 octave at a time, whenpressed.∙ Pressing both Octave buttons at the same time will reset the setting to 0.The maximum you can shift the keyboard is 3 octaves down and 4 octaves up covering theentire MIDI keyboard range of 127 notes.TransposeThe Transpose buttons are located below the Octave buttons. They work the same way:∙ With each press the left Transpose button will transpose the keyboard down one semi-tone.∙ The right Transpose button will similarly transpose the keyboard up 1 semi-tone at a time,when pressed.∙ Pressing both Transpose buttons at the same time will reset the transpose setting to 0 (only if transpose is assigned).You can transpose the keyboard -/+ 12 semi-tones. The Transpose buttons in addition can be assigned to control an additional 4 functions. Check the Setup section of this guide for more details.Pitch bend and Modulation WheelsThe two wheels below the Octave and Transpose buttons are by default used for Pitch bend and Modulation.The Pitch bend wheel is spring loaded and automatically reverts to it’s center position upon release. It’s ideal to bend note s when you are playing phrases that require this kind of articulation. The bend range is determined by the receiving instrument.The Modulation wheel can be freely positioned and is programmed to control modulation by default. The Modulation wheel in addition, is MIDI assignable with settings stored over power cycling so its retained when you switch the unit off.Foot SwitchYou can connect a foot switch pedal (optional, not included) to the 1/4” jack socket on the back of the SE49 keyboard. The correct polarity is automatically detected on boot-up, so if you plug in your foot switch after boot-up is complete, you may experience the foot switch working in reverse. To correct that, do the following:∙ Switch the SE49 off∙ Make sure your foot switch is connected∙ Switch the SE49 onThe polarity of the foot switch should now be automatically detected.56 Nektar SE49 User Guide Setup MenuThe Setup menu gives access to additional functions such as selecting Transpose button functions, control assign, selecting velocity curves and more. To enter the menu, press the [Octave Up]+[Transpose Up] together (the two buttons in the yellow box, right image).This will mute the MIDI output of the keyboard and instead the keyboard now is used toselect menus.When the Setup menu is active, the LED above the button will blink and its color is orangeto indicate setup is active.The chart below provides an overview of menus assigned to each key.Menu keys are the same for both SE49 and SE4961 but value entry using the keyboard is one octave higher on SE4961. Refer to the screen printing on the unit to see which keys to press to enter values.The functions are separated in to two groups. The first group spanning C1-G#1 covers general setup functions.The second group spanning C2-E2 covers the transpose button assignment options.On the following page we cover how each of these menus work. Note the documentation assumes you have an understanding of MIDI including how it works and behaves. If you are not familiar with MIDI, we recommend you study MIDI before making control assignment changes to your keyboard. A good place to start is the MIDI Manufacturers Association C1C2Control AssignYou can assign the Modulation wheel, the fader and even the foot switch pedal to any MIDI CC messages. Assignments are stored over power cycling so the keyboard is set up the way you left it, when you next switch it on.Here is how it works:∙ Press the [Octave Up]+[Transpose Up] buttons at the same time. The LED above the button will blink and the color is orange to indicate setup is active.∙ Press the low C#1 on your keyboard to select Control Assign.∙ Move or press a control to select the control you want to assign a MIDI CC message to.∙ Enter the MIDI CC value using the white number keys spanning G3–B4 (G4-B5 on SE4961).∙ Press Enter (C5) to accept the change and exit Setup.Setting the MIDI ChannelControls as well as the keyboard send their messages on a MIDI channel from 1 to 16. To change the MIDI channel do the following:∙ Press the [Octave Up]+[Transpose Up] buttons at the same time. The LED above the button will blink and the color is orange to indicate setup is active.∙ Press the low D1 on your SE49 keyboard to select MIDI Channel.∙ Enter the MIDI channel value you want (from 1 to 16) using the white number keys spanning G3–B4.∙ Press Enter (C5) to accept the change and exit Setup.Sending a Program Change MessageYou can send a MIDI program change message by doing the following:∙ Press the [Octave Up]+[Transpose Up] buttons at the same time. The LED above the button will blink and the color is orange to indicate setup is active.∙ Press the low D#1 on your SE49 keyboard.∙ Enter the program number you want (from 0 to 127) using the white number keys spanning G3–B4.∙ Press Enter (C5). This will send the message immediately and exit Setup.Sending a Bank LSB MessageTo send a Bank LSB message, do the following:∙ Press the [Octave Up]+[Transpose Up] buttons at the same time.

线性霍尔传感器 1. 概述
ES49E 为小型、通用、线性霍尔效应传感器，其输出 信号电平决定于施加在器件敏感面的磁场强度， 随磁场强度 成比例地变化。当 ES49E 处于零磁场条件时，其输出电压 是电源电压的一半。S 磁极出现在 ES49E 标记面时，输出 电压将随磁场强度增加而线性升高；相反，N 磁极将使输出 电压随磁场强度增加而线性降低。ES49E 具有低噪声输出 的特点，不再需要采用外部滤波。它还包括薄膜式电阻，能 提高温度的稳定性和准确性。 工作温度范围为-40℃至 85℃， 适用于各种商业用户和工业环境。
