sensor_type: ldc1612
# The sensor chip used to perform eddy current measurements. This
# parameter must be provided and must be set to ldc1612.
#frequency:
# The external crystal frequency (in Hz) of the LDC1612 chip.
# The default is 12000000.
#intb_pin:
# MCU gpio pin connected to the ldc1612 sensor's INTB pin (if
# available). The default is to not use the INTB pin.
