Grove-Q Touch Sensor 觸摸感測器 seeed

商品說明

Grove-Q Touch Sensor 觸摸感測器是高靈敏度和高抗噪聲觸摸輸入感測模組。它基於Atmel AT42QT1070。AT42QT1070以擴頻方式調製其突發，以大幅度抑制外部噪聲的影響，並抑制 RF 輻射的干擾。QT1070 採用雙脈衝採集方式。這提供了更大的抗噪聲能力，並且消除了對外部採樣電容器的需求，允許使用單個腳位進行觸摸感測。

示意專案：本套件不含擴展板與Arduino 開發板。

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.
