Description

Historically: inductive  sensing technique has required complex: analog-only circuitry: making it a costly technique for applications outside of industrial controls or portable metal detectors. To provide a low cost inductive sensing solution for designers: this reference design describes the implementation of the ultra-low power single chip solution for inductive proximity sensor by using TI Extended Scan Interface module on MSP430 microcontrollers. This reference design also uses three different LC sensors to demonstrate the compatibility of ESI module and calibration routine with different type and size of inductors
