Working Principle

The MLX90333LDC-BCH utilizes a magneto-resistive sensing element that is sensitive to changes in direction and strength of a magnetic field. It works on the principle of magneto-resistance, or MR, wherein the resistance of a material changes in response to a magnetic field. When the sensor is exposed to a magnetic field, the resistance of the element will change accordingly, and this change will be accurately measured by the sensor.

The sensor uses a three-axis magneto-resistive sensing element which is sensitive to changes in the direction and strength of the magnetic field. The sensing element consists of two pairs of coils that are arranged at right angles to one another. The coils generate an output signal proportional to the strength and direction of the magnetic field.

This output signal is then amplified by the sensor’s electronics and accurately measured by the processor. The output of the processor is sent to the logic circuit, which processes the information and relays it to the user interface. This information is then used by the system to determine the direction and strength of the magnetic field.

Conclusion

In conclusion, the MLX90333LDC-BCH is an excellent choice for applications related to motion sensing, orientation sensing, and magneto-resistive sensing. It offers high accuracy, very low power consumption, small form factor, and a wide operating voltage range. Its working principle is based on the principles of magneto-resistance, wherein changes in the strength and direction of the magnetic field are sensed and measured by the processor. This makes it highly suitable for a variety of applications.
