INTERNAL CIRCUIT
Note: there is no direct line between the power or signals of the probe and the rest of the
circuits. That the probing circuit is being powered by capacitors and the signals handled by

relays powered the capacitor. Once sensing is complete, the enable should be disabled so the
capacitor can be charged again to be ready for next sensing sequence.
