The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module. Allows you to remove the worry of conventional push-type keys. 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 switches 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. In addition to the thin paper ( non-metallic ) covering the surface of the module, as long as the correct location of the touch, you can make hidden in the walls, desktops and other parts of buttons. The TTP223B Digital Sensor Module is a capacitive touch switch that provides a simple and reliable way to add touch-sensitive controls to your electronic projects. This Digital Sensor module utilizes capacitive sensing technology, allowing it to detect touch through a variety of non-conductive materials such as plastic, glass, or even paper. It features a single touch detection pad, which can be easily interfaced with a microcontroller or other digital circuitry. The module operates on low power and offers stable performance, making it suitable for applications where power consumption and reliability are important considerations. With its compact size and easy integration, the TTP223B module is ideal for a wide range of DIY electronics projects, including interactive displays, control panels, and touch-sensitive interfaces. The TTP223B Digital Sensor Module boasts several specifications that make it a versatile component for various projects. It operates with a supply voltage ranging from 2.0V to 5.5V DC, making it compatible with a wide range of power sources commonly found in electronic devices. The module consumes very low power, typically around 1 microampere in standby mode and only a few microamperes during active sensing. This low power consumption makes it suitable for battery-powered applications where energy efficiency is crucial. The module features a single touch detection pad, providing a straightforward interface for users to interact with their projects. It employs a built-in debounce circuit to ensure stable and reliable touch detection, effectively filtering out noise and preventing false triggers. The Digital Sensor touch sensitivity level can be adjusted using external capacitors, allowing users to customize the module’s responsiveness according to their specific requirements. With its compact dimensions (approximately 15mm x 11mm), the TTP223B module is easy to integrate into electronic designs, whether as a standalone touch-sensitive switch or as part of a larger circuit. It communicates with external devices using a simple digital output signal, making it compatible with a wide range of microcontrollers and digital logic circuits. Overall, the TTP223B Digital Sensor Module offers a cost-effective and user-friendly solution for adding capacitive touch sensing capabilities to electronic projects.
