Okdo TS2141-A Capacitive Touch Screen Sensor

The Okdo TelePort capacitive touch sensor adopts the most advanced capacitive sensing technology. Its touch area is based the touch detection chip and can be used a switch. This sensing area can "feel" the touch of people and metal and send high/low voltage levels. Although it is separated by objects, it still can feel the touch. The sensitivity will decrease as the thickness of the object rise. It features the low power consumption and wide working voltage. In addition, after bootingmodule, itwilltake about 0.5 seconds to stabilize.

Compatible with RJ11 6P6C OKdo TelePort Control boards and expansion shields
Digital capacitive touch sensor can be connected to any digital input on a microcontroller
This sensor can "feel" people or metal objects to produce a high/low voltage level
