Inductive Sensing Design Challenge: Portable Detector based on the LDC1000 (#2)

12 May 2014

Since my last post I have been doing some tests with the module and also did some research on using a custom coil.

Below is a drawing of the device. The Detector Circuit will contain a microcontroller, Bluetooth module, LDC1000, piezobuzzer, headphone connection. To balance the device, we can put the power supply at the start of the handle.

You can connect to the device with a smartphone via Bluetooth. It is possible to mount your smartphone to the handle. An App can control the microcontroller and LDC1000. The App can also show measurements and visuals.

I have bought some parts (like copper wire) and will start with building some coils. There are different form factors to test (round, ellipse, dual coil).

DAB look at Clearpath Robotics in Canada, they started off by mapping land mines using an extended network of mobile robots with metal detectors, they have since switched direction a bit, but that may give you some ideas. Check out these links, here here here and here.

If you want more info on how it all worked I can get you more info.

I am very interested in your progress.
I had an idea to mount a coil on a radio controlled car so that I could cover a large area looking for metal objects in the ground.
I like your Bluetooth approach.
I look forward to seeing how much depth penetration and reliable metal contact your design provides.
