创建 802.11 发射器并从 WiFi 路由器读取数据
这个问题有两个部分。请随意给我文章的 URL 或推荐书籍，因为答案可能有点深入，无法快速论坛响应。
1) 我需要感测流经一对电线的瓦数并通过 802.11 传输有关它的数据。我猜涉及到微控制器，但我不知道从哪里开始。无需安全保障。我只希望发射机定期广播数据（例如，每秒 1 帧）。
2) 我需要从 802.11 路由器获取步骤 1 中的数据广播。我希望能够在步骤 1 中对任意数量的发射器执行此操作。步骤 1 中的每个发射器是否都有一种特殊类型的 ID，我可以从 802.11 路由器中查找该 ID？我什至不知道如何在我的路由器上获取“句柄”以查看它正在接收哪些数据。因此，首先，我如何获取我的路由器，然后如何在步骤 1 中看到来自我的发射器的这些可能的多个数据流。
谢谢， 杰伊
There are 2 parts to this question. Feel free just to give me URLs to articles or suggest books, too, as the answer is probably a bit in depth for a quick forum response.
1) I need to sense the wattage flowing through a pair of wires and transmit data about it via 802.11. I guess a micro controller is involved, but I'm not sure where to begin. No security necessary. I just want the transmitter to broadcast the data at regular intervals (e.g., 1 frame per second).
2) I need to pick up the data broadcast in step 1 from my 802.11 router. I want to be able to do this for any number of transmitters in step 1. Does each transmitter in step 1 have a special kind of ID that I can look for from my 802.11 router? I don't even know how to get a "handle" on my router to see what data it's receiving. So, first, how do I get a hold of my router, then how do I see these possibly multiple data streams coming from my transmitters in step 1.
Thanks,
Jay

我不确定（！）我可以回答以上所有问题！
对于微控制器，您可能需要查看开放的 Arduino 平台。 此处记录了一些无线功能。
当您从这些微控制器收集数据时，每个微控制器都将具有唯一的硬件地址和 IP 地址。因此，您可以通过连接服务器的地址来确定哪个是哪个（您很可能会选择 IP 地址）。
所以上面的肯定是可行的。然而，这是相当多的工作。
I'm not sure (!) I can answer all of the above!
For the micro-controller, you may want to look at the open Arduino platform. There's some wireless capability documented here.
When you collect the data from these micro-controllers, each will have a unique hardware address and an IP address. So you can determine which is which by the address of the connecting server (most likely you'll pick up the IP address).
So the above is certainly feasible. However it's quite a lot of work.
您正在寻找的是嵌入式wifi。搜索需要一段时间，但您应该能够准确找到您想要的内容，因为那里有相当多的可用设备。

What you are looking for is embedded wifi. It will take awhile searching, but you should be able to find exactly what you want, as there is a fairly good variety of devices available out there.

听起来像是 XBee 的工作（请参阅此处.) 这些设计用作低功耗无线传感器。如果幸运的话，您甚至不需要外部微控制器，因为它们可以传输在自己的 I/O 引脚上读取的数据。
有一些集中器可以让它们连接到普通的有线或 WiFi 网络。
Sounds like a job for XBee's (see here.) These are designed to operate as low power wireless sensors. If you're lucky you wont even need an external microcontroller as they can transmit data that they read on their own I/O pins.
There are concentrators available that allow them to be connected to normal wired or wifi networks.
