MLX90393 module is a powerful, versatile, ultra-small, universal 3D hall effect sensor module that can be easily fitted into any DIY projects where 3D position detection is required. It provides 44,000uT maximum full-scale resolution with a resolution rate of 0.161uT and requires only 100uA of current.

Compared with the size, it has a very powerful magnetic field sensing ability that can easily detect very small magnetic fields and provides the data via SPI and I2C protocols.

It works as a compass sensor but can also be used as a non-contact controller, linear actuator position sensor, or a flow meter with a magnetic impeller.

Interfacing Diagram

MLX90393 Interfacing Diagram

The interfacing is quite easy using an I2C bus. The MLX90393 IC can easily be interfaced with any microcontroller having an I2C interface. However, this IC can also be interfaced using SPI protocol.

If the targeted microcontroller does not use I2C pull up resistors, R1 and R2 can be added.
