AT42QT1010-TSHR Application Field and Working Principle

Capacitive touch is widely used in industrial electronics, consumer electronics and applications requiring non-contact detection. The AT42QT1010-TSHR is a highly integrated touch sensor designed to enable designers and manufacturers with the advanced gesture recognition technology they need to differentiate their products and solutions. This touch sensor supports a capacitive touch keypad with both I2C and GPIO interfaces, making it easy to integrate into any system, and supports superior noise resistance for gesture detection. It has many features, including small, low power, low cost, etc., making it very ideal for many applications.

Application Field

The AT42QT1010-TSHR sensor can be used in a wide range of applications areas, including industrial, medical, home and consumer applications. It is suitable for sensing the presence of a human finger in electronic and industrial control. It can also be used for camera shutter buttons and gaming controllers, or to detect the movement of an object or a user’s gesture.

Working Principle

The AT42QT1010-TSHR touch sensor uses changes in capacitance to detect the presence of a finger or other capacitive object. The capacitive touch sensor is made of two parts, the RX capacitor and the QT1010-TSHR self-capacitance measuring ASIC. The RX capacitor is a pad made of a layer of conductive material, and the ASIC is attached directly to the pad, which measures the capacitance between the RX capacitor and the QT1010-TSHR ASIC. When an object, such as a finger, approaches the capacitive sensor, the capacitance between the RX capacitor and the ASIC changes. This change is detected by the ASIC, and a signal is sent to the system, indicating the presence of an object near the surface of the sensor. Based on the change in capacitance, the ASIC is able to determine if the capacitive object is moving, pressing, or removing, and can generate a variety of different signals to the system, depending on the action detected. The QT1010-TSHR ASIC also has a variety of features to enable advanced gesture detection and touch recognition, including low-power operation, a surface map for use in multi-touch applications, and an advanced noise-cancelling system that allows for reliable gesture detection in noisy environments. Additionally, the ASIC can detect multiple points of contact, meaning that it is possible to detect multiple fingers on the same touch sensor, or detect complex gestures such as zooming and rotating.In conclusion, the AT42QT1010-TSHR touch sensor provides a reliable and cost-effective solution for capacitive touch-enabled systems in a wide range of applications. With its advanced features and low-power operation, it is an excellent choice for designers and manufacturers looking to differentiate their products and solutions. The excellent noise cancellation, multi-touch support, and gesture detection make the AT42QT1010-TSHR a powerful and versatile tool for any system.
