Capacitive Touch Sensors and Proximity Sensor ICs are common sensing technologies in modern electronics that use changes in capacitance to detect the presence and location of a target object without physical contact. Provides innovative solutions for user interface design and automation control. Capacitive Touch sensor is an electronic device that works based on the principle of capacitance, which recognizes the touch action by detecting the change of capacitance between the object and the sensor. Its core is to use the electric field change generated when the human body or object is close to, resulting in the change of the sensor capacitance value, and then converted into electrical signals for processing. Proximity Sensor ICs is an integrated circuit designed to detect the proximity of an object. By transmitting and receiving specific forms of energy (such as infrared, ultrasonic, or electromagnetic fields), it analyzes the time and intensity of the signal return to determine the distance and position of the object.
