Industry’s Best CapSense

CapSense Component Config Tool

CapSense Component Configuration Tool in PSoC Creator

The PSoC 4000 family delivers the industry's best capacitive-sensing technology, CapSense, to implement buttons, sliders and proximity sensors. Supporting mutual-capacitance sensing, robust water proofing and SmartSense™ Auto-Tuning, CapSense works under severe environments and speeds time-to-market with no manual tuning required.


Application Example: Coffee Machine

PSoC Enables:

  • Liquid-tolerant capacitive touch interface for buttons and sliders
  • Proximity detection
  • LED control
  • Door lock control
