10-cm Capacitive Proximity Detection Reference Design (TIDM-PROXIMITYSENSING)

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.


Low power, simple capacitive proximity sensing application Leverages unique pin oscillation I/O available on MSP430 Value Line MCUs Demonstrates greater-than 10cm proximity range detection Implements the "Fast RO" method for a portable, battery powered consumer product Includes all hardware & software design files PC-side GUI is also available to aid in development
