Hall Sensor DVR5013 ?

Other Parts Discussed in Thread: DRV5013

Hi,

I want to use the hall effect sensor DRV5013 for making a metal detector which detects ferrous and non-ferrous metallic objects by sensing the variations in geomagnetic field. I am not sure if this sensor is suitable for this purpose as I have just conceived this idea myself. Reading the data sheet does not answer this to me as well. Can anyone give remarks on this ?

Also, I could not find the evaluation or development boards that could be purchased to evaluate this sensor and do basic prototyping. Any ideas guys ?

Kind Regards

    Hi Umair,

    One thing you might want to consider is that ferromagnetic elements are usually not magnetized naturally.  Iron, cobalt, and nickel in the ground won't produce much of a magnetic field unless they are magnetized with a strong magnetic field.

    A field of 4mT is needed to guaranteed turn-on the DRV5013AD.

    We don't currently offer an evaluation board for this 3-pin device.  However you can get free samples of the through-hole version (TO-92) and attach to the leads directly or use with a breadboard.

    Best regards,
