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?
Hi.The address of I2C touch sensor is irrevocable,so you can't work more than one synchronously
Hi my friend,we have new vesion can replace it please refer:http://www.seeedstudio.com/dep... a nice day!
Can this feeler sense the touch behind some glass cover? I'm thinking of ~4mm thick windows glass as cover.
I didn't get it... :P
The wiki shows an example with a paperboard pice. Suposing that the glass isn't conductive (as metal / requirement), doesn't it really work with a glass pice?
I'd like the same application, with a glass cover.
Do you now sell individual touch feelers (or packs of 4, but without the sensor board)?
Hello , sorry that we don't sell individual touch feelers . You can made it by your self ,just on connected a wire to the port of the board , and it can be touch similar as Touch Feeler.
Thanks you, I got it now. FYI actually I had a problem with the zip-file. I was unable to extract using window7-build-in unzip but it work with 7-zip portable. The software is working so I'll dive into it...
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
Hi there, 12 touch feelers can be supported by one I2C Touch Sensor. The problem is that we do not sell the touch feelers sepparately now ,that is strange. I will feedback to our marketing department to solve this problem .
Can i connect 16 sensors(2xTwig) to one microcontroller?
Yes if you know how to code with them, that is no problem.
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?
The working voltage is 3~5V. If you view the wiki that you can see it(Sorry for the wiki link,it was wrong before).
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 ?
And, I'm thinking about using a CAT5-like cable for long distances...
You can restart to upload the origital dso203 firmware and upgrade.
