Gravity: Conductivity Switch Sensor

SKU: SEN0223

The Gravity Conductivity Sensor Switch module detects if an object has electrical conductivity (max 10MΩ), working with good conductors (coins, wires, metal) and conductors like human body, fruit, plants. Touch its terminals to change output—use for interactive apps (fruit pianos, musical wind chimes, game controllers). As a Gravity Sensor Family member, it has Gravity Interface features (plug-and-play, color pins, reverse polarity protection). Use Gravity IO Expansion Shield to connect more sensors and have fun!
