TTP223 Capacitive Touch Sensor Module

About this product

Capacitive touch sensor module based on the TTP223 chip. Detects finger touch on the copper pad and outputs a clean digital HIGH/LOW signal. Serves as a drop-in replacement for a tactile push button. Ideal for projects where a mechanical button is unsuitable.

Ultrasonic, IR, temperature, humidity, motion, current, camera and RF sensor modules - plus relay, logic-level and breakout boards for prototyping and production.
