Description

Grove - Q Touch Sensor -------------------- ![enter image description here][1] 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. Specification Operating Voltage: 3 ~ 5.5V Operating Current @3.3V: 1mA Touch Keys: 7 Keys ; key0 ,key1 ,key2 are on the Xadow PCB bottom side Communicating Protocol: I2C I2C Address: 0x1B For more detail, please visit: http://www.seeedstudio.com/item_detail.html?p_id=1854 [1]: /editor/20160503/572872b40d168.jpg
