• Elevate your projects with the TTP223 Capacitive Touch Sensor Switch Module – a reliable, low-power solution for adding sleek touch controls without the hassle of mechanical buttons! This compact module uses advanced capacitive sensing technology to detect finger proximity or touch on its 24mm etched touch pad, delivering a clean digital high/low signal to your microcontroller.
• Powered by the TTP223 IC, it features adjustable sensitivity for reliable detection even through non-metallic surfaces like plastic or glass (up to 5-10mm thick). Choose between self-lock mode (touch once to toggle on/off) or momentary mode (hold for continuous output) – perfect for switches, sliders, or gesture interfaces. With ultra-low standby power (just 3-5uA), it’s ideal for battery-powered IoT devices, wearables, or always-on systems.
• Connecting is simple: VCC to 3.3V/5V, GND to ground, and SIG to any digital pin on Arduino/ESP32. Read the state in your code and respond to touches instantly – no libraries needed! Whether you’re building smart home panels, interactive toys, or custom keyboards, this module offers durability (no wear from presses) and waterproofing for harsh environments.

FAQ  

1. What is the difference between self-lock and momentary mode?  
   Self-lock toggles output on each touch (like a flip switch); momentary keeps output high only while touched.
2. Can it detect touch through a panel?  
   Yes, up to 5-10mm through non-conductive materials like acrylic or wood.
3. Does it require a library for Arduino?  
   No, it’s a simple digital input – just read the SIG pin like a button.
4. What voltage levels does the output support?  
   Digital output matches input voltage: 3.3V logic for low-voltage MCUs, up to 5V.
5. Is it sensitive to water or humidity?  
   Fully waterproof – capacitive sensing ignores water droplets.
6. How do I switch modes? 
   Most modules default to self-lock; some have a jumper or resistor mod for momentary.
7. What’s the power consumption for battery projects?  
   Extremely low: 3-5μA standby, making it perfect for long-life applications.
8. Can it work with ESP32 or Raspberry Pi?  
   Yes, fully compatible with 3.3V GPIO pins.
9. Does it have debounce built-in?  
   Yes, integrated debounce prevents false triggers from shaky touches.
10. What if the touch area is too sensitive/large?  
    Adjust by adding a resistor on the sensitivity pin or covering part of the pad.
