Are you tired with clicking mechanic button? Try our capacitive touch sensor. Right now we can find touch sensor on most electronic device. So uprade 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 sensetivity well decrease as isolation get thick.For momentary touch module, it outputs HIGH when human touch detected while LOW when human touch released, there is also the toggle touch module that outputs changes every time when human touch detected.Specification2.0–5.5V DC supplyResponse time max about 60mS at fast mode, 220mS at low power mode @VDD=3VLow power consumption2.0cm x 2.0cm twig modulePower indicator ledUseful LinksMomentary Touch Sensor SchematicTTP223 Datasheet
