Hi, what is the behaviour of the sensor if the magnetic field is below 5 mT? From the video, it looks like the rule of thumb applies for rotary applications. What if the application is about to measure the 3D magnetic field considering multiple sensors (e.g. to make the measurement robust to common disturbance sources)?

Hi Nick, In millimeters, how far away from the sensor can the MLX90395 magnetic sensor accurately identify a magnet?

Hi, great video. What should be the dimension of the magnet for a Joystick application and also what about the space between the magnet and MLX90395/MLX90393 when we tend to use a magnet axially magnetized?

You will indeed need some simulations to define the right magnet (size,..) See the application notes on the product page www.melexis.com/MLX90394

Hi, What's the accuracy you can get in degrees for on-axis applications? Can it achieve 1 degree of accuracy for on-axis rotary application? Assuming it's powered with a 3.3-3V battery. I guess the choice of IC for such an application will be MLX90363?

Hi Doraditya, We can confirm that these accuracies can be achieved after a proper calibration. Depending on the application MLX90363 might be a good choice but MLX90392 is possible too.

Is it used for detecting the presence of different minerals of our body?

I know this video is a bit dated and for a singular product, but does Melexis offer anything for simultaneous 6dof (xyz linear and xyz rotation) movement? If not, in what way could a set of chips (not necessarily the 90395, any product) be utilized to handle simultaneous 6dof movement? I remember years ago, if not over a decade at this point, Fraunhofer IIS had their HallinOne sensor that, in theory at least, could handle 6dof, though I've never been able to find a standalone IC for their product. Fraunhofer also has a IC diagram showing how individual sensors are placed within the chip, IIRC 12 sensors in various orientations, are Melexis products designed in a similar way, in theory at least, compared to the HiO sensor? I'm only asking for a better understanding of the IC package itself, I found the HiO design interesting, though Fraunhofer never really explained the data side of their implementation, so I'm curious if Melexis has a similar or different approach to 3D magnetic sensing.

The MLX90395 measure the magnetic field in three directions (X, Y, and Z), using horizontal Hall elements combined with and integrated magnetic concentrator, and outputs these measurements as a digital value relative to the magnetic field strength. . The actual position (angular or linear displacement) can be calculated using the data that is provided by the sensor. More information on our IMC (integrated Magnetic Concentrator) can be found here: www.melexis.com/en/tech-talks/triaxis-position-sensing-solution

@@Melexis_Sensors This doesn't really answer my question of if the chip is capable of simultaneous 6dof or not, and none of your materials explain if this is possible either. It's really as simple as a yes or no answer, yes it can do simultaneous 6dof, or no the chip is limited to a certain degree of freedom. I just want to know if I can have both a spatial position of a magnet and 3D rotation (better described as a quaternion) of said magnet, simultaneously. Or does your product lack the amount of sensors that would make this possible. I.e. is this similar to the Fraunhofer IIS product, which does true spatial measurements with a higher number of sensors (IIRC 12 sensors), or is it more similar to the products that Texas Instruments and Infineon produce where it's only one sensor per axis and thus has a more limited degree of freedom?

@@xaytana Thanks for reverting back, please allow us to give a bit more background to the previous answer. As already indicated in your previous reply you were using a reference of the HallinOne approach from Fraunhofer. This HiO cell is nothing more than a combination of 2 vertical hall sensors and 1 horizontal hall to measure the 3 different magnetic field components. In our Melexis solution we are not using vertical hall technology but we are using our IMC technology in combination with planar hall technology our concentrator allows us to convert horizontal field lines into a vertical component which we then use to measure the 3 different field components. So both principles (HallinOne or our Triaxis technology) will give you the raw data signals for the 3 different field components. The Integrated Magnetic Concentrator is offering a certain gain and is resulting in better performance (offset and sensitivity) compared with vertical hall technology. So to answer your question our chip will provide the data for Bx,By and Bz allowing you to use the 3 vectors (simultaneously) for further post processing.

hi Nick, is it possible to use this sensor for car detection? If possible, how far away do you think it would be accurate?

@Tom Vanagt Hello Nick, Actually, I was wondering if it could be used for the same purpose, to detect vehicles. please correct me if i misunderstood The larger the Tesla value, the more the sensing distance of the sensor is, isn't it? So, MLX90395 has 120mT but MLX90392 has 5mT, so MLX90395's sensing range is not higher?
