Description
Touch Control Made Simple
Say goodbye to clicking buttons and wearing out mechanical switches. This module utilizes capacitive sensing technology to detect the touch of a finger. It works reliably even through thin non-conductive materials like glass, plastic, or acrylic, allowing you to create hidden “stealth” buttons for your smart home devices or custom enclosures.
Universal Compatibility
With a wide operating voltage range of 2V to 5.5V, this sensor is compatible with almost every logic level. Whether you are using a 3.3V ESP32, a 5V Arduino UNO, or even a simple battery-powered circuit, this module integrates seamlessly.
Plug-and-Play Convenience
Unlike many sensors that arrive as loose parts, this module comes with header pins already soldered. You can plug it directly into a breadboard or use standard jumper wires to connect it to your development board immediately.
Key Features
-
Solid State Reliability: No moving parts to wear out over time.
-
Fast Response: Detects touch instantly with no delay or “bouncing” issues common in mechanical switches.
-
Digital Output: Outputs a simple HIGH/LOW signal (easy to read with
digitalReadon Arduino). -
Low Power: Efficient design suitable for battery-operated devices.
-
Ready to Use: Pre-installed 3-pin header for instant connection.
