Grove - Q 터치센서 ( Grove-Q Touch Sensor )

Grove-Q Touch Sensor


The Q Touch Sensor is a high sensitivity and high noise immunity touch input device.It is based on Atmel AT42QT1070. The AT42QT1070 modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise, and to suppress RF emissions. The QT1070 uses a dual-pulse method of acquisition. This provides greater noise immunity and eliminates the need for external sampling capacitors, allowing touch sensing using a single pin.
  • Operating Voltage: 3 ~ 5.5V
  • Operating Current @3.3V: 1mA
  • Touch Keys: 7 Keys ; key0 ,key1 ,key2 are on the Grove PCB bottom side
  • Communicating Protocol: I2C
  • I2C Address: 0x1B
