The Grove - 12 Key Capacitive I2C Touch Sensor V3 (MPR121) is a multi-channel proximity capacitive touch sensor. It's a 3-in-1 module with the following features: Capacitance Sensing. Tough Sensing.

Features:
  • Internal 10-bit ADC
  • Integrated independent autocalibration for each electrode input
  • Completely independent electrodes with built-in autoconfiguration
  • I2C interface, with IRQ, Interrupt output to advise electrode status changes
  • Hardware configurable I2C address
  • 12 electrodes/capacitance sensing inputs in which 8 are multifunctional for LED driving and GPIO
  • Autoconfiguration of charge current and charge time for each electrode input
  • Separate touch and release trip thresholds for each electrode, providing hysteresis and electrode independence
  • Add two more GND pin and expand the gap of pins for safe handling

Typical Applications:
  • PC Peripherals
  • MP3 Players
  • Remote Controls
  • Mobile Phones
  • Lighting Controls
