LDC1000 Click, MIKROE-1583, MikroElektronika
The LDC1000 Click is a compact add-on board that measures the inductance change a conductive target causes when it moves into the inductor's AC magnetic field. This SPI-configurable sensor requires only the frequency between 5kHz and 5MHz to begin sensing, demonstrating the use of inductive sensing technology to sense and measure a conductive target object's presence, position, or composition. It comes with an example of a PCB sensor coil designed to provide the user with maximum flexibility. Also, onboard IN pins allow you to replace the offered detachable sensor and solder your own.
This Click board is suitable for contactless, short-range sensing that enables high-resolution position sensing of conductive targets, even in harsh environments.
