Capacitive Touch Slider - CAP1203

Overview

The Capacitive Touch Slider - CAP1203 is a versatile and reliable sensor module designed to bring intuitive touch interfaces to your electronics projects. Unlike mechanical buttons, this capacitive sensor detects touch through non-conductive materials, enabling sleek, hidden controls. With three independent channels that can be configured as separate buttons or as a slider, the CAP1203 offers flexibility for a wide range of applications. Whether you are building a custom control panel, a smart home device, or an interactive art installation, this sensor provides a responsive and durable solution that works even under surfaces like wood, acrylic, or glass up to 6mm thick.

Key Features

• 3-Channel Capacitive Sensing: Each channel can be used independently or combined to create a slider interface.
• Works Through Non-Conductive Materials: Detect touches through wood, acrylic, glass, and other materials up to 6mm thick, perfect for hidden controls.
• I2C Interface: Simple two-wire communication with microcontrollers, saving GPIO pins.
• Low Power Consumption: Ideal for battery-powered projects with sleep modes.
• Adjustable Sensitivity: Configure touch thresholds via I2C to suit different materials and environments.
• LED Indicator: Onboard LED for visual feedback during touch detection.
• Compact Design: Small form factor, easy to integrate into any project.
