ای سی تک ورودی تاچ،کلید لمسی تکی،کلید لمسی مجاورتی با قابلیت تشخیص دست انسان تا فاصله 12 میل متر با روکش شیشه و فاصله 6 میلی متر با روکش پلاستیک The AT42QT1010 is a digital burst mode charge-transfer sensor that is capable of detecting near proximity or touch, making it ideal for implementing touch controls.
The QT1010 is designed specifically for human interfaces like control panels, appliances, toys, lighting controls, or anywhere a mechanical switch or button may be found. It includes all hardware and signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. Only a single low-cost capacitor is required for operation
