TTP223B Capacitive Touch Sensor Module
Add elegant, button-free touch control to your projects with the TTP223B Capacitive Touch Sensor Module. This compact, single-channel touch sensor detects finger contact through its sensing pad and outputs a clean digital signal - perfect for replacing mechanical buttons in Arduino, ESP32, and Raspberry Pi builds. Available at The Engineer Store, Bengaluru with fast shipping and full technical support.

| Support | Email & WhatsApp 24/7 |
Key Features
- True Capacitive Sensing: Detects the electrical properties of a human finger - no physical pressure required, eliminating mechanical wear and bounce issues.
- Ultra-Wide Voltage Range (2.0V-5.5V): Works natively with both 3.3V and 5V logic systems without any level shifting, making it universally compatible.
- Configurable Output Modes: Solder jumper pads on the PCB let you switch between momentary mode (output HIGH only while touching) and toggle/latch mode (touch once for ON, touch again for OFF).
- Active High or Active Low Output: A second solder jumper configures whether the output goes HIGH or LOW on touch detection - adapts to any circuit logic requirement.
- Micro-Power Consumption (~1.5uA standby): The TTP223B IC draws almost no current when idle, making it ideal for battery-powered and energy-harvesting projects.
- Fast Response with Auto-Calibration: Responds to touch in approximately 60ms and automatically calibrates its baseline capacitance at power-up to account for environmental conditions.
- Simple 3-Pin Interface: Only VCC, GND, and SIG - connect directly to any GPIO pin and read it as a digital input. No libraries, protocols, or complex wiring needed.
- Compact & Breadboard-Friendly: The tiny 24mm x 24mm footprint with standard 2.54mm header pins drops directly into breadboards or perfboards.
- Can Sense Through Non-Metallic Materials: Mount behind thin plastic, glass, acrylic, or wood panels (up to ~2-3mm) for completely sealed, waterproof touch interfaces.
Why Choose This?
- 100% authentic TTP223B modules sourced from trusted, authorized suppliers
- 1-5 day shipping, 7-8 day delivery across India from our Bengaluru warehouse
- Expert technical support included - wiring help, code examples, and troubleshooting
- Tested and verified before dispatch for reliable out-of-box performance
- Perfect entry point into capacitive sensing - no prior experience needed
Project Ideas
- Touch-Activated LED Lamp: Build a sleek desk lamp that turns on/off with a single finger tap - use toggle mode for latching control without any mechanical switch.
- Smart Home Touch Panels: Mount multiple TTP223B modules behind an acrylic panel to create a custom wall-mounted touch controller for lights, fans, and appliances via relay modules.
- Arduino Touch-Based Musical Instrument: Assign different tones to multiple touch sensors and build a capacitive piano or drum pad that plays sounds through a piezo buzzer or speaker.
- Proximity-Activated Display Wake: Use the sensor to detect when a user approaches and wake up an OLED or LCD display from sleep mode - great for IoT dashboards and kiosks.
