Description
The 8-Way Capacitive Touch Sensor TTP226 Module is a reliable, touch-based input solution designed to replace traditional push buttons. Using the TTP226 capacitive touch IC, it offers 8 independent touch-sensitive keys with stable digital outputs, making it ideal for interactive control panels, DIY electronics, robotics, and smart home projects.
Unlike mechanical switches, it provides high sensitivity, fast response, and long durability since it has no moving parts. Compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers, this module is perfect for modern touch-based applications.
Features
The TTP226 is a touchpad detector IC which offers 8 touch key.
The touching detection IC is designed for replacing the traditional direct button key with a diverse pad size. Capacitive touch allows electronics to sense when your finger is within a few millimetres of a surface to simulate a button “press” just like how the pushbutton works.
Capacitive sensing may be used in any place where low to no force human touch sensing is desirable. Onboard 8 key TTP226 capacitive touch induction IC.Onboard 8-way level indicator. Working voltage: 2.4 to 5.5 V. Modules, you can set the output mode, key output mode, the longest time and fast/low power output
