10-cm Capacitive Proximity Detection Reference Design
Texas Instruments
This reference design: featuring the Value Line MSP430 MCUs (MSP430G2xx) with unique PinOsc capability: can implement a simple mechanism to measure capacitance. This capability not only allows for touch detection: but also provides enough sensitivity to support proximity applications. This implementation demonstrates a 10+ cm proximity range.
Features
- Low power: simple capacitive proximity sensing applicationLeverages unique pin oscillation I/O available on MSP430 Value Line MCUsDemonstrates greater-than 10cm proximity range detectionImplements the Fast RO" method for a portable: battery powered consumer productIncludes all hardware & software design filesPC-side GUI is also available to aid in development"
Applications
- Dashboard camera
- Smartwatch
- GPS personal navigation device
