Uni Hall Click Board

Uni Hall Click Board

Uni Hall Click Board, mikroE
Uni Hall Click Board, mikroE

After the BI HALL click, a new click also based on the Hall effect: the UNI HALL Click Board from mikroE. It offers the user an easy way to introduce a unipolar Hall switch to the design. The board is equipped with the Melexis US5881 unipolar Hall-effect sensor that is sensitive to north pole magnetic fields. It outputs a LOW logic level when exposed to a north-pole magnetic field, whereas a HIGH logic level when the north pole is taken away or a south pole is introduced. UNI HALL click also features a 74LVC1T45 single-bit, dual supply translating transceiver. The board uses mikroBUS INT line for communication with the target board microcontroller. It is designed to use either a 3.3V or 5V power supply, which is selectable through a solder jumper.

UNI HALL click can be utilized in countless ways by placing magnets in strategic spots. It is an ideal option to make durable push buttons, or regulate RPM by mounting it on a wheel, or detecting liquid level by attaching it to a float. In its simplest application, UNI HALL click can be engaged as part of a durable contactless proximity switch.

IC/Module: Melexis US5881 Unipolar Hall-Effect Switch

A unipolar Hall-effect switch, the CMOS-technology based Melexis US5881 integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output driver, all in a single package. It is a good choice for use in automotive and solid state switch applications.

Sensitive to North Pole Magnetic Field

Unlike BI HALL click, the unipolar Hall switch aboard UNI HALL click only reacts to north pole magnetic fields, outputting a LOW logic level. In cases where the magnetic field is not strong enough, or of wrong polarity, the click board outputs a HIGH logic level through the mikroBUS INT line.

Communication Interface

The UNI HALL click uses the mikroBUS INT line to communicate with your target board. It uses either a 3.3V or a 5V power supply, which is selectable via a solder jumper. The selection determines logic level voltage.
