The I2C Touch Sensor is based on FreeScale MPR121, to feel the touch or proximity of human being fingers. This sensor include 2 parts: one Touch Sensor controller, and 4 finger feelers. Insert the connectors of feelers into base of Sensor controller, you can begin your touch controlling.
MPR121: The MPR121 is a capacitive touch sensor controller,features internal intelligence, include an hardware configurable I2C address, an expended filtering system with debounce, and completely independent electrodes with auto-configuration built in .
Touch Sensor feeler: The Touch Sensor feelers, which was 4 included in Touch Sensor module,can be set in any place you like, to feel your finger's touch or proximity. Notice it must not get in touch with any conductive material.

Since the address pin is hard wired how can we set the the address to use multiple"Grove - I2C Touch Sensor"on a single I2C bus?
May I have Schematic file like others??
Can this feeler sense the touch behind some glass cover? I'm thinking of ~4mm thick windows glass as cover.
Do you now sell individual touch feelers (or packs of 4, but without the sensor board)?
The unit comes with 4 touch feelers but how many can be directly attached to it,
other 4 as the number of connectors suggest? Or more, by soldering to board pins?
And if I want to buy more touch feelers, do you sell them sepparately? If so, wh
Can i connect 16 sensors(2xTwig) to one microcontroller?
I know this chip needs 3.3 volts but I see in the literature for this product that it can operate at 5v on the I2C line. Is this true and will the product last at 5v?
I'm thinking about using these as switches for my home automation system. Can we make the cable long enough between the feelers and the INT ? 1m, 5m, 15m ? Or between the INT and the seeeduino ?
