NEW TTP223B Digital Touch Sensor capacitive touch switch module for Arduino /RS

About this deal

The TTP223B is a compact, single-channel capacitive touch sensor module built around the TTP223-BA6 IC. It is a single-channel capacitive touch detector designed to replicate a tactile button without any moving parts, making it ideal for applications where mechanical wear is a concern or where a sealed enclosure is needed. The module runs on a supply voltage of 2 to 5.5V DC, and in its normal state the output is low; when a finger touches the pad the output goes high, and if no touch is detected for 12 seconds it switches to a low-power mode. The module supports jog-type operation, behaving similarly to a momentary button, and can be mounted beneath non-metallic surfaces such as plastic or glass, making it suitable for hidden or flush-mounted installations. It is a widely used module that provides a convenient way to add touch-sensitive capabilities to DIY electronics projects, and connects directly to Arduino and similar microcontroller boards via a simple three-pin interface covering power, ground, and digital signal output.
