Capacitive-based human proximity detection for system wake-up & interrupt reference design

This TI Design uses Texas Instruments' capacitive-to-digital converter technology to provide a high-precision method to wake up systems when human interaction occurs. TIDA-00220 demonstrates techniques for alternative sensor design, environmental compensation, and electromagnetic interference protection.

Features
    • Detects Human Proximity using conductive nickel-print sensor, enabling flexible industrial design
    • Sensor itself can be copper PCB material or other conductive materials
    • Reduces environmental effects through several techniques
    • Sensing range is dependent on sensor geometry (20 cm with tested hardware)
    • Low power consumption of 6.2 mW
    • This fully tested and characterized sub-system includes hardware design files (schematics and layout), firmware, and detailed user's guide with test results
