A digital capacitive touch sensor from DFRobot's Gravity series. It detects touch through the same capacitive sensing technology used in smartphones — even through thin cloth or paper. The sensor outputs a digital high/low signal, making it a simple drop-in replacement for mechanical buttons in Arduino and Raspberry Pi projects.
Part of the Gravity ecosystem, the sensor features a standard 3-pin digital interface that connects directly to Gravity-compatible expansion shields. It operates at 3.3–5 V, making it compatible with Arduino, Raspberry Pi, and other 3.3 V platforms.
Key Features
- Capacitive Touch Detection – Senses touch through thin materials like cloth or paper
- Digital Output – High/low signal for easy integration
- 3.3–5 V Compatible – Works with Arduino, Raspberry Pi, and other boards
- Gravity Interface – Plug-and-play with Gravity expansion shields
- Immersion Gold PCB – High-quality, corrosion-resistant surface
Specifications
- Supply Voltage: 3.3–5 V
- Interface: Digital
- Dimensions: 22 × 30 mm
Package Contents
- 1× Capacitive touch sensor
- 1× Digital cable

Jargon buster
Plain-language definitions for the technical terms used above.
- capacitive sensing
- Capacitive sensing detects changes in electrical capacitance, in this case caused by different amounts of water in the soil near the sensor plate. It matters because it avoids exposed metal probe contacts, which can corrode in damp soil over time.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
