- Instant Touch Response: TTP223B capacitive sensor detects finger proximity (0-3mm) through non-conductive surfaces, outputting 3V-5V TTL signals for microcontroller integration. Flexible Power Management: Voltage Range: 2.0-5.5V DC (compatible with 3.3V/5V logic boards) Current Draw: 4mA@active / <1.5μA@standby (prolongs coin cell lifespan) Robust Mechanical Design: Mounting: 4× M2 threaded holes (2.2mm pitch) for acrylic/wood panel fixing Terminals: Gold-plated VCC/GND/IO pins with 2.54mm spacing for breadboards Durability: FR-4 fiberglass PCB withstands 10k+ touch cycles Technical Specifications: Output Logic: HIGH=0.8VCC (3V:2.4V), LOW=0.3VCC (3V:0.9V) Sink Current: 8mA max @3V (directly drives LEDs/relays via buffer) Operating Temp: -20℃~70℃ Smart Home Integration: Replace mechanical switches in humid environments (bathroom/kitchen) Create invisible controls behind ceramic tiles or car dashboards Pair with triacs/SSRs for touch-controlled AC lamps (220V/10A) Development Tools: Includes Arduino sample code for: Capacitive slider prototypes Touch-activated security systems Gesture-controlled IoT appliances Package Contents: 10 × TTP223B touch modules (pre-soldered) + wiring diagram. Safety Note: Avoid metallic surface contact to prevent false triggers. Use 100kΩ pull-down resistor for stable IO signal processing.

Momentary Touch Control: TTP223B chip enables instant on/off response (60ms touch mode) with auto low-power switching after 12s idle. Wide Voltage Compatibility: Operates at 2-5.5V DC (3V typical) with 0.8VCC high/0.3VCC low TTL output for Arduino/Raspberry Pi integration. Non-Metallic Installation: Detect touch through glass/plastic/paper (≤3mm) via 24×24mm PCB with four M2 screw holes for secure mounting. Ultra-Low Power Design: Consumes <1.5μA in standby mode (220ms wake-up time), ideal for battery-powered IoT devices. Bulk DIY Bundle: 10x touch modules (24×24×7.2mm each) for stair lighting, smart mirrors, and capacitive control panels.
