Touch button, also known as the sensor, allows you to control different devices through response to touch, individuals. Due to the lack of mechanical moving parts, differs high reliability and durability unlike the ordinary electric buttons. Finds application, in particular, tablets and smartphones. Every physical touch to the touch sensor through the user's fingers or a special stylus that is registered through the entry system of the processor, and then handled in accordance with the instructions given in the firmware, depending on the applied pressure, hold time, and the direction and length of the path traveled on the screen using the user's finger or stylus.

What are the most popular types of touch sensors, and on what principle work?
Among the two most popular technologies of the touch buttons, there are buttons capacitive and resistive. The capacitive buttons operate on the principle of detecting the presence of materials on the dielectric constant significantly different from air, and such properties, is, in particular, the human body, including the fingers. Maneuvering your fingers across the glass surface of the buttons, causes local changes in the strength of the electrostatic field on the surface and changes the electrical capacitance between the touch fields that are constantly monitored by the microprocessor therefore, to correctly determine the coordinates, which changes the capacitance. The basis of this technology is the majority of touch displays, including tablet devices, industrial control panels or mobile. Another technology of touch sensors, and resistive buttons which use glass and plastic surface covered with oxide indocyny on the opposite layer relative to the layer touch. A glass fiber layer, also covered with oxide indocyny. When a finger or stylus presses on the plastic surface and come in contact with this surface with the surface of the glass and the measuring system measures the resistance between these surfaces, providing sensory input to the microprocessor, similarly as in the case of sensors, capacitive.
Modules touch buttons for embedded systems
Touch button you can use in various projects covering the manual control device. Multi-channel modules, switches, offered in the store, Botland Arduino-compatible due to the possibility of communication via I2C and SPI. Thanks to these sensors, you can create the interface of the shutters and other elements of building automation, to build a pocket size synthesizer music, and even build a simple game for training reflexes for two people. In our offer you will find also specialized chips that are compatible with touch control.
