We're continuing our line of clicks based on the Hall effect. Today, it's UNI HALL click.
UNI HALL click carries a unipolar Hall switch. While BI HALL click, released yesterday,
is sensitive to both magnetic poles, the US5881 IC on this one only reacts to north pole
magnetic fields, outputting a LOW logic level. When the field is not strong enough, or of
wrong polarity, UNI HALL click outputs a HIGH logic level through the mikroBUS™ INT line.
You can use unipolar Hall switches in countless ways just by placing magnets in strategic
spots. Attach a magnet to a wheel and you can infer RPM. A magnet attached to a float can
indicate rising and falling liquid levels. Also, Hall switch based push buttons are highly reliable
and long lasting—ideal for heavily abused pinball machine buttons for example.
