Capacitive touch sensor for Arduino

I am in a search of capacitive touch sensors. The functionalities I'm aiming at are
The capacitive touch should be able to recognize up, down and sideways slides on the Grid. Has anyone used the this type of module? If yes please do suggest me. Thanks in advance...!!
This can be done using captive grid. You can buy a touch pad
or you can make your own PAD
please refer 13th page of this documentation.
if you like to make one MPR121 is a nice choice
Design C is also good,

@Akhil Thanks. I am not in a state to design my own capacitive touch so I am going with already made modules. But the one which you have posted is too very expensive for my application. Are there any other modules that are a bit more cheaper.

Hey @kowshik1729, why don't you use a five of the touch keys(shown below), form them up in the shape of a cross and get the sequential data across two of those sensors to detect a left/right or up/down swipe?

@SuperGops Woow that's a great idea...I shall try this out..!!
@sreu13 I edited comment please read that again. Most probably it will not effect your file system. In some scenarios it can create worse effect.
@arunksoman i'll try this method, but while executing swap command, will the rasbian os and the files it contains be effected??
Ensure that you are installed tensorflow 1.x since screenshot of your code shows something like
from keras.layers.convolution import covolution2D
It is not correct in case for tensorflow 2.0 since keras api is part of tensorflow itself.
Another thing is try to expand your file system. It should be do with your own risk.sudo raspi-config Navigate to Advanced options Select advanced options and hit enter(I believes tab key is useful here) Choose Expand File System and hit enter finish. Then your pi may prompt to reboot. If it didn't run. Execute
sudo reboot Then execute following commands one by one: $ sudo apt-get purge wolfram-engine $ sudo apt-get purge libreoffice* $ sudo apt-get clean $ sudo apt-get autoremove Then increase swap memory by editing following file swapfile:
$ sudo nano /etc/dphys-swapfile It will open nano editor. Navigate to variable CONF_SWAPSIZE=100
It indicates your current swap is only 100mb.#CONF_SWAPSIZE=100 CONF_SWAPSIZE=2048 Save the file and exit nano editor. sudo reboot
So you just have to increase by commenting down this line and increase to appropriate value something like shown below for 2GB swap:
I believes if it did not helped you, you have to think about MOVIDIUS or NVIDIA Jetson nano etc.
@arunksoman tensorflow 2.0.0 version had been installed
I will look more into it. Thanks again
