Capacitive Touch Sensor

Capacitive Touch Sensor

Introduction :

Digital Capacitive Touch Switch Module is based on TTP223B.

Normally,it outputs low and keeps at low power state.

When a touch is sensed on the circular marked region, it outputs high and switch to the quick response state. When not being touched for 12 seconds, it switches to low power state again.

If the module is mounted in the surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.

Capacitive Touch Sensor (TTP223-B) is a touch-sensitive device that detects human touch and can be used in various electronic applications such as smartphones, tablets, and touch screens. This sensor works by measuring the change in capacitance that occurs when a finger or other conductive material comes in contact with the sensor’s surface.

The TTP223-B Capacitive Touch Sensor module is small in size and easy to use, making it an ideal choice for DIY projects and prototyping. It has low power consumption and is sensitive to even the slightest touch, making it perfect for applications where space is limited or where user input is required.

The TTP223-B Capacitive Touch Sensor can be used to create a wide range of projects such as touch-sensitive switches, touch-sensitive lamps, and touch-sensitive robotic arms. It is also widely used in the automotive industry for creating touch-sensitive buttons and switches.

Overall, the TTP223-B Capacitive Touch Sensor is an excellent choice for any project that requires touch sensing capabilities in a compact and easy-to-use package.? Capacitive touch sensors are a popular technology for detecting touch on electronic devices. The TTP223-B capacitive touch sensor module is a reliable and cost-effective solution for adding touch input to your projects. This module is designed with a low power consumption and can be easily interfaced with any microcontroller. The TTP223-B sensor features a self-calibration function, making it more reliable and immune to noise interference. It can detect the presence of a finger through a thin layer of glass, plastic or paper, making it ideal for use in a variety of applications such as consumer electronics, medical devices, and industrial controls. With its compact size and easy-to-use interface, the TTP223-B capacitive touch sensor module is a great choice for any project that requires touch input.
