Touch Switch Sensor Module

Description

About this item:

The Touch Sensor Module is a capacitive touch input device that detects when a human finger makes contact with its surface. Instead of using mechanical buttons, it sends a digital HIGH/LOW signal directly to a microcontroller, making it a reliable, durable, and user-friendly input option.

Specifications & Features:

• Sensor Type: Capacitive Touch Sensor

• Common IC: TTP223 (popular model)

• Operating Voltage: 2.0V – 5.5V (commonly 3.3V or 5V)

• Output Type: Digital (HIGH when touched, LOW when untouched—or vice versa)

• Response Time: < 60ms (touch), < 220ms (release)

• Current Consumption: ~1.5 µA (low-power mode), ~3.5 mA (active)

• Interface Pins: VCC, GND, SIG (Output)

• Output Voltage Level: TTL compatible (direct Arduino connection)

• Dimensions: ~24 mm × 24 mm (may vary by design)

• Touch Surface: Copper pad or metal plate (some modules include extended pad options)

Applications:

• Capacitive button replacement for electronics

• Touch-activated lamps or switches

• User input for Arduino and IoT devices

• Interactive DIY projects

• Robotics control panels
