{"title":"Gravity: Digital Capacitive Touch Sensor For Arduino","handle":"gravity-digital-capacitive-touch-sensor-for-arduino","url":"/products/gravity-digital-capacitive-touch-sensor-for-arduino","description":"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.\n\nPart 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.\n\nKey Features\n\n\nCapacitive Touch Detection – Senses touch through thin materials like cloth or paper\n\nDigital Output – High/low signal for easy integration\n\n3.3–5 V Compatible – Works with Arduino, Raspberry Pi, and other boards\n\nGravity Interface – Plug-and-play with Gravity expansion shields\n\nImmersion Gold PCB – High-quality, corrosion-resistant surface\n\n\nSpecifications\n\n\nSupply Voltage: 3.3–5 V\n\nInterface: Digital\n\nDimensions: 22 × 30 mm\n\n\nPackage Contents\n\n1× Capacitive touch sensor\n1× Digital cable\n\n\nResources\n\nProduct wiki\nSchematic (PDF)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13862,"title":"Default Title","sku":"DF-DFR0030","price":5.96,"on_sale":false,"in_stock":true,"available_quantity":230,"option1":"Default Title"}]}
