If it does not, try reversing the pole. The opposite side of the sensor will respond to the other pole of the magnet. TIMER CIRCUIT A sensor can be used to trigger a timer for a specific duty. A Hall ...

Using the SS49E linear Hall effect sensor in pairs on four sides of a square, the setup proves quite straightforward. Above the fixed sensor plate is a moveable magnet plate centred by a set of ...

The circuit below is built around a far-famed voltage comparator LM393 IC. It is responsible for taking the WCS2702 current sensor input. It also controls an optional switching mechanism to protect ...
