Touch Sensor Module (TTP223)

About this product

Capacitive touch sensor module based on the TTP223 chip — drop-in replacement for a tactile push button. Detects finger touch on the copper pad, outputs a clean digital HIGH/LOW signal. Great for projects where a mechanical button feels wrong.

Ultrasonic, IR, temperature, humidity, motion, current, IMU and environmental sensors for prototyping, research and production.
