DFRobot Gravity Digital Capacitive Touch Sensor for Arduino

The DFRobot Gravity Digital Capacitive Touch Sensor is a compact touch input module for Arduino, operating across 3.3 V to 5 V. It provides a one-touch style switch for button-less control in embedded designs, IoT devices, and electronic projects.

Overview

Using capacitive sensing, the sensor detects a touch and outputs a high or low digital voltage signal to the connected microcontroller. Its digital output simplifies coding, allowing users to focus on functionality and user experience. The module suits prototyping and hobby projects that need intuitive input without mechanical buttons.

Key Features

• Detects touch through insulating materials such as cloth or paper, with sensitivity decreasing as the barrier becomes thicker
• 3-pin Gravity digital interface for plug-and-play connection with compatible DFRobot shields and connectors
• Operating voltage of 3.3 V to 5 V, suitable for Arduino boards and other 3.3 V or 5 V logic systems
• High/low digital output level
• Standard assembly structure with two 3 mm mounting holes spaced at 5 mm intervals

Specifications

• Interface: 3-pin Gravity digital interface
• Operating voltage: 3.3 V to 5 V
• Output signal: High/low level
• Dimensions (W x D x H): 3.3 x 1.5 x 4.3
• Weight: 11 g

Applications

Suitable for embedded system design, smart electronics, IoT solutions, and educational hobby projects, the sensor can be used where a concealed or protected touch interface is required. Its compatibility with a range of Arduino boards and 3.3 V or 5 V logic systems makes it a straightforward addition to new or existing builds.

Choose the DFRobot Gravity Digital Capacitive Touch Sensor when you need a compact, button-less touch input for Arduino projects with a simple digital interface.
