Key benefits Reliable, lowpower touch input: capacitive touch sensing with antiinterference design provides stable operation while minimizing power consumption in standby. Simple integration: a compact base module that fits into spaceconstrained designs and can be added to existing projects or builds with minimal wiring. Precise control: builtin potentiometer lets you adjust sensitivity to match different materials, mounting arrangements, and user preferences. What it does Detects a touch and provides a single channel digital output for switching or signaling. Works across a wide supply range (2.5 V to 5.5 V), making it compatible with common microcontrollers and singleboard computers. Lets you tune responsiveness to avoid false triggers or increase sensitivity for gloved/farsurface operation. Key specifications Sensing method: capacitive touch Outputs: single channel Supply voltage: 2.5 V to 5.5 V Sensitivity adjustment: builtin potentiometer Design highlights: compact base module, antiinterference circuitry, low standby power Who it's for Electronics hobbyists and makers building custom panels or interactive projects. Developers and integrators adding a touch input to automation systems or equipment. Raspberry Pi and microcontroller users who need a simple, lowpower touch switch interface. Practical applications Home automation: mechanical switches with a slim touch switch for lights or smart home devices without redesigning the whole wall plate. Industrial/bench equipment: add a clean, durable touch control to equipment dashboards where dustresistant, contactless input is preferred. DIY control panels and prototypes: interface with Raspberry Pi, Arduino, or other controllers to create custom control surfaces and interactive installations. Why choose this module Broad voltage compatibility simplifies power sourcing in mixedvoltage projects. Adjustable sensitivity and antiinterference design reduce false activations and adapt to different installation conditions. Compact form factor and singlechannel output make it easy to incorporate into tight enclosures and simple control schemes. What to expect in use A small PCBstyle module that connects to your controller and provides a reliable touch input line. Simple tuning via the onboard potentiometer to balance sensitivity and stability based on your enclosure materials and distance from the touch surface. Compatibility notes Operates directly with most microcontrollers and singleboard computers that accept a digital input within the 2.5–5.5 V range. Use appropriate wiring and mounting to preserve capacitive sensing performance (avoid large grounded planes directly over the sensing area). This module is a straightforward, lowpower capacitive touch solution for projects that need a single, adjustable touch input with reliable operation in noisy or spacelimited environments.
