AJMRTC set includes 20 pieces of TTP223 capacitive touch sensor modules. It uses capacitive induction principle to detect finger touch without mechanical pressing. Users can switch between two working modes: momentary jog mode and self-lock toggle mode by modifying the onboard solder jumper. An indicator LED lights up when touch is detected, helping you check the working state conveniently. It runs on 2.4V to 5.5V DC power and sends digital high/low level signals to MCUs such as Arduino, ESP32 and STM32. It has strong anti-light interference and stable sensing performance. Widely used for smart touch lamp control, DIY touch switches, interactive toys, equipment trigger buttons and embedded human-machine interaction projects.
