Description TTP223B Capacitive Touch Sensor TTP223B Capacitive Touch Sensor Are you tired of clicking a mechanic button? Try our capacitive touch sensor. Right now we can find touch sensors in most electronic device. So upgrade your Arduino project with our new version touch sensor and make it cool!! This little sensor can “feel” people and metal touch and feedback a high/low voltage level. Even isolated by some cloth and paper, it still can feel the touch. And the sensitivity will decrease as isolation get thicker. Improvement List Wide voltage range from 3.3V to 5V Standard assembling structure (two 3mm holes with multiple of 5cm as interval) Icons to simply illustrate sensor function High-quality connector Immersion gold surface Specification Supply Voltage: 3.3V to 5V Interface: Digital Size:22x30mm
