  • Pushing out the small circuit board, we get to the meat of this miracle measurer:

  • A Micronas HAL1820A programmable linear hall sensor

  • This takes advantage of the Hall effect to track the wheel as it turns, using that to determine how fast you're traveling (and how hard you're working).

  • The three wire system is connected with a simple JST connector, not solder. Now that's what we call modular.

推出小电路板，我们得到这个奇迹测量器的核心：

一个HAL1820A可编程线性霍尔传感器

这利用霍尔效应在车轮转动时跟踪车轮，使用它来确定你的行驶速度（和你的工作努力程度）。

三线系统使用简单的 JST 连接器连接，而不是焊接。现在这就是我们所说的模块化。
