Gravity: Digital Capacitive Touch Sensor
This little sensor can “Feel” people and metal touch and feedback a High / Low voltage level. Even isolated by cloth or paper, it still can feel the touch. The sensitivity will decrease as the isolation getting thick.
Gravity: Digital Blue LED Light Module
This Blue LED light module has a shiny blue color.
