Shanaa eSpot TTP223 Capacitive Touch Sensor Switch Module | Touching Button Self-Locking Micro Controller Board Electronic Hobby Kit

A capacitive touch sensor switch module is a type of electronic component used to detect touch or proximity. It typically consists of a capacitive touch sensor IC (Integrated Circuit), along with supporting components such as resistors, capacitors, and sometimes LEDs or other indicators. These modules are designed to detect changes in capacitance when a conductive object, like a finger, comes into proximity with the sensor.
