  • 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.

Durch das Herausdrücken der kleinen Leiterplatine kommen wir an die Innereien dieser mysteriösen Messeinheit:

Ein 1820A programmierbarer linearer Hall-Effekt-Sensor

Dieser macht sich den Hall-Effekt zunutze, um das sich drehende Rad zu verfolgen. Diese Daten werden genutzt, um festzustellen, wie schnell du dich bewegst (und wie sportlich du bist).

Das Dreileitersystem ist mit einem einfachen JST-Stecker verbunden, nicht gelötet. Das nennen wir mal modular!
