10PCS TTP223B Capacitive Touch Switch Module - 2-5.5V Digital Sensor with M2 Mounting Holes for DIY Smart Home/Non-Metal Surfaces
Special Features
- 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.
