Compact singlechannel capacitive touch sensor module designed for reliable, lowpower touch detection with adjustable sensitivity and strong interference resistance. Key benefits Reliable touch detection: Capacitive touch technology plus an antiinterference design gives stable operation in noisy electrical environments. Low standby power: Compact base module consumes minimal power in standby, reducing overall system draw. Simple integration: Singlechannel output and wide voltage compatibility (2.5 V–5.5 V) make it easy to connect to Raspberry Pi, Arduino, and other microcontrollers. Precise control: Builtin potentiometer lets you tune sensitivity for different materials, distances, and environmental conditions. Spacesaving and durable: Small form factor fits into tight enclosures and is suitable for repeated use in both domestic and industrial settings. Compatibility and function Voltage range: 2.5 V–5.5 V input — compatible with common logic levels. Output: Single channel touch output for straightforward wiring to a digital input or interrupt pin. Adjustment: Onboard potentiometer for sensitivity calibration without extra components. Design: Engineered for environmental adaptability and reduced false triggers. Typical applications Smart home retrofit: mechanical switches with a touch interface for lamps, lighting circuits, or scene control panels. Automation and control panels: Add a clean, durable touch button to machinery dashboards, kiosks, or custom control panels where space and reliability matter. Prototyping and maker projects: Ideal for Raspberry Pi and microcontroller projects that require a single tactile input with adjustable sensitivity. Who this is for Electronics enthusiasts, developers, and Raspberry users building interactive interfaces, automation systems, or custom control panels that require a compact, lowpower touch input solution.
