Capacitive-Based Human Proximity Detection for System Wake-Up & Interrupt Reference Design
Description
This reference design uses our capacitive-to-digital converter technology to provide a high-precision method to wake up systems when human interaction occurs. TIDA-00220 demonstrates techniques for an alternative sensor design: environmental compensation and electromagnetic interference protection.
Features
- Detects human proximity using a conductive nickel-print sensor that enables a flexible industrial designThe sensor can be copper PCB material or other conductive materialReduces environmental effects through several techniquesSensing range is dependent on sensor geometry (20 cm with tested hardware)Low-power consumption of 6.2 mWThis fully tested and characterized design includes hardware design files (schematics and layout): firmware and detailed user guide with test results
Applications
- Refrigerator & freezer
- Residential & living fan
