TIDA-00466, Noise-immune Capacitive Proximity Sensor System Reference Design

TIDA-00466, Noise-immune Capacitive Proximity Sensor System Reference Design. The FDC2214 proximity and capacitive sensing design demonstrates the use of capacitive sensing technology to sense and detect the presence of various objects. The design is a complete hardware and firmware solution. The firmware processes the data from one proximity sensor and two capacitive touch buttons via the FDC2214 to determine whether an object is in the intended sensing area. Dedicated colored LEDs light up once the device detects a target in close proximity to the board or detects a press on the buttons. The design is powered by one AA-battery
