AJMRTC 10Pcs TTP223B Capacitive Touch Sensor Module, Digital Capacitive Touch Switch Module, Single Channel Touch Button Detector Board for Arduino ESP32 Raspberry Pi DIY Smart Home Project

AJMRTC TTP223B capacitive touch module adopts single-channel capacitive induction technology, which identifies finger touch by detecting capacitance variation. It features no mechanical wear, longer service life and can be hidden behind non-metallic materials such as plastic, acrylic and glass to realize sealed waterproof touch panels. It provides digital CMOS level output and only occupies one IO pin of the main controller. You can switch between jog mode and self-locking toggle mode, and swap active high or active low trigger through onboard solder jumpers. Built-in automatic recalibration function effectively reduces false triggers caused by humidity and temperature changes. It works seamlessly with Arduino, ESP32, STM32 and Raspberry Pi, widely used for smart lamp switches, access control panels, interactive electronic works and STEM teaching experiments.
