In this video, I've explained how to use TTP223 captive touch module circuit. This module has 4 types of working modes. I explained all these modes on breadboard.

This is very helpful, I was about to use this module for my up coming DIY project.

@rupash88 3 года назад

By far the clearest explanation regarding this module. Thanks from New Zealand.

Great 👍

@scottrackham1887 3 года назад

thank you this makes so much more sense why the button was only a touch to on and when i removed my finger it shut off!!. thank you so much

Great video i now know all about how the switch works, but could you tell me why you need to put a risistor in. i have a capacitive switch module that i am trying to connect to a keyboard control module but cant seem to get it to work please help.

@EDUdotcom 2 года назад

Can you share how you soldered the tiny connectors? They are so small. You make soldering the sound so easy.

@Fahad-sc4yw 3 года назад

Very helfull for our project... Sir can u tell some application of this sensor

@zhekadk 3 года назад

What body capacity it requires? Will it react on a mouse (meaning that little animal)?

@rapunzeleh546 3 года назад

i bought some of the 223b touch sensors from aliexpress a few years back and finally found a use for them... just to see if they worked, i tested it with my bench power supply, at 5v, black to ground and red to vcc. doesn't seem to recognize touch at all... tried another - same thing... tried a third, same thing... so clearly i must be expecting something different... shouldn't it still work even though it's not connected to the signal? must be doing something wrong, what are the chances three of them don't work... any ideas? all i want to do is make a short strip of 5v led light strip tape turn and off.... how hard can that be?

Hello , with the touch sensor , if i wanted to connect a 0.5mm wire to the touch part , what part of the circuit board would i need to solder the cable to . I want to control a relay giving an automatic door an activation signal from an insulated push plate on the door . The cable connected to the push plate to the touch sensor .

@SerenoOunce Год назад

Only has 3 modes. Does not work with both A *and* B shorted at the same time. Since B functions as the latch condition, no need to short A in that use case anyway.

@lint2023 3 года назад

Great examples. Do you know how much maximum current the module can pass? I haven't been able to find this information.

@EEWave 3 года назад

I think it is very little. To control a load, it is better to use a transistor with output pin.

@sanjaybatra6593 Год назад

I tired it in position B....its v sensitive ....even if finger is little bit away from switch ( approximately 0.25 inch ) ...its get switched ON/OFF. So Can it be used for commercial project ? Can some noise or something else can make it ON/OFF. my purpose is to switch ON/OFF power supply to microcontroller board...

@SarojKumar-rz8dh 3 года назад

So this modul works with 5 v

@SartajSaif 3 года назад

How many voltage maximum

@SarojKumar-rz8dh 3 года назад

Sir what is mean by initially

@ilyasshaikh172 2 года назад

Please suggest any practical application of this circuit ( AC load control ) , and from where to get working voltage for the module

@deepkumarkoijam1999 24 дня назад

Buy 220v relay module or make one yourself 😊

@ZX11CAN 2 года назад

Using this sensor, it will turn LOW after 6-7 seconds. The touch light goes off as well. Did you experience this with the TTP223?

@jsavoni6478 3 года назад

All my chips are together. Am I suppose to just cut them?

@EEWave 3 года назад

Please send your chips picture to my Instagram so that I can help you. Instagram link in the description below.

@parooog 3 года назад

Sir , in case of Touch to ON mode (initially low) I want to control only one LED using four TTP223 sensor modules ... Then what will be the circuit ? Please help sir !!

@EEWave 3 года назад

Hi Parag, for that you have to use OR Gate logic circuit. No need to use OR gate ic, just 4 Diode is enough.

@parooog 3 года назад

@@EEWave sir , where and how to connect those 4 diodes ?

@parooog 3 года назад

@@EEWave You mean N side of each diode at i/o pin of each Touch sensor and P side with LED and then all the touch sensors are in parallel with each other ?

@sanjaybatra6593 Год назад

can this module be modified to remember last state.........if it was ON and suddenly power goes...it will be ON when power comes ...like this and vice versa ?

@deepkumarkoijam1999 24 дня назад

Solution Mila kya vy last state remember karne ka

@HasanAhmed-ex6jv 2 года назад

Thank you for the explanation, I need help with the electronics on trying to make this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zD9cv4JiNfE.html I need to activate LED's where touched and remain on until the object/hand is lifted. Also connecting multiple boards would help. I am a novice with electronics so I may need diagrams lol
