Upgrade your control interface with the Double Button Capacitive Touch Sensor Module — a reliable, modern alternative to traditional mechanical buttons. Designed for Arduino and DIY electronics, this module uses advanced capacitive sensing to create responsive, touch-based input controls with effortless precision.

Key Features and Benefits

  • Dual Touch Buttons – Two independent touch-sensitive pads with red indicator LEDs activate on touch, ideal for interactive projects.
  • Capacitive Proximity Sensing – Detects touch within 0–5 mm, enabling smooth, wear-free operation without physical contact.
  • Dual-Sided Activation – Both front and back sides of the PCB serve as functional touch surfaces, enhancing design flexibility.
  • CT8224-3 Chipset – Built with a CT8224-3 IC that outputs a simple digital signal, easily compatible with Arduino, Raspberry Pi, and similar microcontrollers.
  • Hidden Installation – Mount under non-metallic materials (plastic, glass, acrylic, or thin paper) for a seamless, modern finish in your projects.
  • Compact Design – Includes 4 mounting holes and low power consumption, perfect for embedded systems and control panels.
