Mikroe MIKROE-3310 3D Hall 3 Click board™
Mikroe MIKROE-3310 3D Hall 3 Click board™ is an accurate magnetic sensing Click board™ used to measure the intensity of the magnetic field across three perpendicular axes. This Mikroe board has a low-power 3D magnetic LIS2MDL sensor from STMicroelectronics and a triple 2-channel multiplexer/demultiplexer 74HC4053 IC from NXP. The board features an embedded self-test, support for the hard iron compensation, selectable power mode, 16-bit data output, and a wide dynamic range of measurement (±50 gauss). The MIKROE-3310 3D Hall 3 Click board is ideal for various position-sensing applications, contactless knobs, encoders, switches, and potentiometers. This Click board is also ideal for other magnetic field sensing applications based on accurate spatial sensing.
The LIS2MDL sensor from STMicroelectronics has a separate hall sensing element on each axis. This sensor offers a basis for accurate positional calculations with an accurate and reliable measurement of the magnetic field intensity in a 3D space. The internal magnetic field sensing elements are multiplexed and connected to a 16-bit low-noise Analog-to-Digital Converter (ADC). This will sequentially sample each sensor by providing 16-bit spatial data over the digital interface.
The 74HC4053 IC from NXP is used with the RST pin of the mikroBUS™ to perform both SPI READ and SPI WRITE functions. This allows the demultiplex of the SDI/SDO pin of the LIS2MDL and routes the two resulting pins to the appropriate pins of the mikroBUS™ (SDI and SDO).
