UNI Hall 3 Click Designed for Precise Contactless Magnetic Sensing and Position Detection
UNI Hall 3 Click is a compact add-on board developed by MIKROE, designed for precise, contactless magnetic sensing and position detection. It is built around the A31015KEWALT-47SN, a nanopower, ratiometric linear Hall-effect sensor manufactured by Allegro MicroSystems. The board's sensor is configured for high-reliability south-pole magnetic sensing, making it particularly suitable for applications that require continuous magnetic measurement alongside low-power operation.
UNI Hall 3 Click's core sensing capability is its continuous analogue output, which provides a signal proportional to magnetic field strength. This lets a host microcontroller measure changes in magnetic field strength for accurate position sensing and proximity detection. The sensor offers a typical bandwidth of 15kHz, enabling the host MCU to assess both magnetic position and rapid target movement, a defining characteristic of the board's high-frequency signal response.
Power management is a critical aspect of the board's design, featuring dedicated GPIO pins for enable and sleep modes. These controls provide developers with the ability to manage the sensor's operating state, which is intended to maximize power efficiency in battery-operated systems. Furthermore, the board supports selectable 3.3V or 5V power supply and logic levels via an onboard hardware jumper, offering flexible voltage-level options for system integration.
To simplify hardware integration, UNI Hall 3 Click incorporates ClickID technology for automated hardware identification and a detachable Click Snap layout for flexible off-board sensor placement. These features enhance developer flexibility in incorporating magnetic sensing into their designs. The combination of its sensing functionality, power-control capabilities, selectable operating voltage, and modular hardware arrangement positions UNI Hall 3 Click as a comprehensive solution for contactless position and proximity measurement.
