HOW DOES IT WORK?
3D Hall 4 Click is based on the SENM3Dx, a 3D Hall magnetic sensor from SENIS. The sensor incorporates three groups of mutually orthogonal Hall-effect elements, of which one is horizontal and two are vertical. Each of them has biasing circuits and amplifiers. Those elements are very compact, allowing for the sensor's very high spatial resolution. In addition, by incorporating some other techniques, the sensor features high angular accuracy, significantly suppressing offset, low-frequency noise, and the planar Hall effect.
The sensor provides high analog frequency bandwidth from DC to 220kHz and has a built-in temperature sensor that measures the chip temperature. Over the TEMP OUT switch, you can select the host MCU to read the temperature or connect the sensor temperature output to the TEMP connector for testing. There are also two 3-pin headers for analog and digital output of all three magnetic field dimensions. Finally, there is VCM, a virtual ground, and VREF, a bandgap reference voltage pin.
3D Hall Click uses an SPI serial interface to communicate with the host MCU and is compatible with SPI mode 1. The sensor is a 5V device, and to allow 3.3V MCUs to work with the sensor, the 3D Hall Click is equipped with the TXB0104, a 4-bit bidirectional voltage-level translator from Texas Instruments. The temperature output of the sensor, host MCU, can read over the AN pin if selected over the TEMP OUT switch.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
