Mini Touch Sensor Module with Header Pin

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 digitalRead on Arduino).

• Low Power: Efficient design suitable for battery-operated devices.

• Ready to Use: Pre-installed 3-pin header for instant connection.
