TIDM-INDUCTIVEPROX
MSP430 Microcontroller Single Chip Inductive Proximity Sensing Reference Design
TIDM-INDUCTIVEPROX
Overview
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
Features
- Ultra-Low Power
- Single Chip solution
- Non-contact detection
- Insensitive to Environmental Contaminations
- Compatible with different type and size of LC sensors
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
