Capacitive Touch Sensor Module (TTP223B)

The TTP223B Capacitive Touch Sensor Module detects human touch using capacitive sensing technology. When a finger touches the sensor pad, the capacitance changes and the module outputs a digital signal. This sensor can be used as a touch switch, replacing mechanical buttons in electronic devices. It provides fast response, high reliability, and low power consumption, making it suitable for modern electronic interfaces. The module is widely used in touch-controlled lamps, smart home switches, interactive electronics, and automation systems. Key Features Capacitive touch detection Can replace traditional push buttons Fast response time Low power consumption Digital output signal Compact and easy to interface Technical Specifications Parameter Value Operating Voltage 2V – 5.5V Output Type Digital Sensor Type Capacitive Touch Response Time ~60 ms Interface VCC, GND, OUT Pin Configuration Pin Description VCC Power Supply (2V–5.5V) GND Ground OUT Digital Output
