AT42QT1012-MAHR

AT42QT1012-MAHR capacitive touch sensor is one of the latest offerings from the AT family of sensors. It has been designed to provide the user with a reliable, low-cost solution for sensing a variety of objects or materials in a range of different experimental or industrial settings. This versatile touch sensing module can be used in a wide variety of scenarios and applications, from automotive, industrial and medical markets to hobbyists and artificial intelligence research.

The AT42QT1012-MAHR touch sensor module is built around one of Atmel\'s QTouch capacitive sensing devices. It utilizes a Low Resistance Input structure ARID (Atmospheric Radiance Interference Detection) technology. The AT42QT1012-MAHR relies on the proven idea of capacitance change due to proximity of the human body. This module functions by first transmitting a small current, 30kHz-750kHz, from an oscillator onto the sensing pad, and then analyzing the signal that is returned. The analysing of the signal consists of looking for changes in signal frequency, signal amplitude and capacitance, as these are said to represent the presence of a human body in the same general vicinity as the sensing pad.

The AT42QT1012-MAHR has a range of applications and settings. The module can be used to sense any object: ranging from finger touches, door handles and counter tables, to pressure, control knobs and other objects and materials. It is suitable for a variety of settings such as gaming devices, vending and access control machines, keypads, industrial automation, medical equipment and even robotics.

Due to its low power requirements and the fact that it both detects and differentiates between multiple touches, the AT42QT1012-MAHR is a perfect choice for any industry where low power and accuracy are paramount. The adjustable touch detection threshold also allows the user to optimize and calibrate the module to suit the specific needs of their application.

The AT42QT1012-MAHR is an incredibly useful module that can be used almost anywhere and offers the ideal solution for a wide range of applications. It is a low-cost, low-power, accurate and versatile capacitive touch sensing module that can provide reliable results in a range of different settings, and is ready to meet the needs of all modern industries and applications.
