TTP223 - Touch 1Channel (MINI)

The TTP223 mini touch sensor module is a capacitive touch switch that detects human finger touch without any mechanical contact. It works by sensing changes in capacitance when a finger approaches the sensor pad and converts this into a digital output signal (HIGH/LOW).

• Sensor Type: Capacitive touch sensor
• IC Used: TTP223
• Operating Voltage: 2.0V – 5.5V DC
• Output Type: Digital (HIGH when touched / configurable LOW)
• Output Modes: Momentary or latch (toggle mode selectable)
• Touch Sensitivity Range: ~0–10 mm 
• Module Size: Very small
