I ordered a few of these on a whim, which arrived yesterday, and now I can't wait to get home from work to try incorporating these into my WiFi switches. Going to work much better than I anticipated after watching this.
Great video! I am trying to power a DC: 3,5-9V mini water pump with a 18650 3,6V Battery. Do you know what specific MOSFET do I need to use to make the TTP223 work? Thanks!
Hi Larmkillen, thank you for your sharing. My Induction cooktop capacitive switch failed and it cannot sense when I press the glass. I would like to use this fantastic switch button to replace it. Is it work, if I use the superglue to stick it on the glass panel?
Hello, I bought these sensors for an application in my company but I do not understand why when I attack the sensor on a surface (as you did with the wooden board), this recognizes the presence and operates immediately. How come you can make it operate only when passing the finger? Can you give me some advice? Thank you
Sorting B is only for toggle... If you are telling that "the sensor working without touching with finger"... Then I've to tell you that this board is very sensitive... Make sure the surface is totally non-conductive... Even a metal touch triggers it... Not even need to body contanct or grounding...
Thank you for showing this. I found this by searching through what kind of materials can we make this TTP223 work. You mention you were making a bluetooth speaker. Project finished? Can we see it? :)
Probably you figured it out, but i'll answer anyway. At the beggining, the wood alone triggered my sensor. Seems like the sensor needs some seconds to calibrate to the new capacitance. I sticked it to the wood and it was fine :)
Hi - yes, I've tested these and they do change sensitivity after a while if unused... and to me - FAR too much in the "sensitive" direction - if lying on a bench and triggered - they may actually stay on. The backlit ones seem more reliable in that sense but then they cost a little more. Still - at the price I'm sure we'll find a use for these...
Har inte prövat det ännu :D kanske funkar bäst genom aluminium i sådant fall. Det är köpta från eBay. Postar en länk till likadana här: www.ebay.com/itm/10-Pcs-TTP223-Capacitive-Touch-Switch-Button-Self-Lock-Module-For-Arduino-l8-/311674238223?hash=item48913b750f:g:YjsAAOSwgZ1XrHz0
I have tried. It does not work since the glass by itself will trigger the sensor. Yes I have even left overnight expecting the sensor to calibrate but it's not doing it.
According to the chip's datasheet, if the capacitor is replaced by a connection, a piece of wire for example, sensitivity increases. But if you use a capacitor, the manufacturer (Tontek) recommends a maximum of 50pF.

Thank you for the video. It's working fine here, trough a 6mm MDF.

May I know how does it work? Capacitive sensor? Wire through the drilled hole for sensor module?
i got pack of 10, i haven't yet tested if they can auto-calibrate themselves to larger pad that can be hidden inside wall for a light switch
Hi, my sensor gets triggered by any surface. Any solutions?
Hello from Brazil!
Thank you so much for shared!!! It´s just that i needed know!
I tried it with 8 and they seem to interconnect with each other. I can't manage to work them by itself or independent.
Thanks for sharing 🙏
thanks but i have one question , can i use this sensor behind the glass having thickness of 4mm
Yes it works through glass or plexiglass
Excellent explanation...👍👍
In my case, it seems like the wood itself is triggering the sensor, weird.
Hi Larmkillen, thank you for your sharing. My Induction cooktop capacitive switch failed and it cannot sense when I press the glass. I would like to use this fantastic switch button to replace it. Is it work, if I use the superglue to stick it on the glass panel?
It will work, but check the voltage before... TTP223 works between 2.2-5.5v

Thank you
Semerfil Srl Italia I have the same problem right now. Did you find a solution? I have no idea right now
Maybe u r talking about toggle mode.... If u short "B" lebel on board, u activate toggle mode...
I have the same problem. I shorted the B, but the problem is the same.
Sorting B is only for toggle...
If you are telling that "the sensor working without touching with finger"...
Then I've to tell you that this board is very sensitive...
Make sure the surface is totally non-conductive...
Even a metal touch triggers it... Not even need to body contanct or grounding...
If the surface continueslly triggering the board, try after shorting "A" pin... Hope that'll works...

will it work 12v ?
Hi i have a ttp223B blue one and need to touch it trough a glass how can i test it do you habe any solutions for me???
Can it sense other object besides a finger? Thanks!
Hi and thanks for sharing.
How did you stick the TTP223 to the wood?
spidermev Regular superglue
Thanks for sharing 👍🙏
What about 2 mm plastic?
My chip get triggered by the wood :( help !
Great video !
Did it work trough plastic?
Hey, That's great. thanks you.. I want to use it with car's windscreen. Would it work?
No. The glass by itself will trigger the sensor. I have tried.
I have no idea how you did this - I have to touch mine for them to work - any gap and they don't work

@@cristian-bull thank you a lot ❤️
Grymt! Funkar den med metall också? vart köpte du den?
Har inte prövat det ännu :D kanske funkar bäst genom aluminium i sådant fall. Det är köpta från eBay. Postar en länk till likadana här: www.ebay.com/itm/10-Pcs-TTP223-Capacitive-Touch-Switch-Button-Self-Lock-Module-For-Arduino-l8-/311674238223?hash=item48913b750f:g:YjsAAOSwgZ1XrHz0
Hello Larmkillen!, its a great video, have you ever tested on a 6mm glass surface?
Pherp De Lara Hey! no i have not tried it but it should work just fine :)
I have tried. It does not work since the glass by itself will trigger the sensor. Yes I have even left overnight expecting the sensor to calibrate but it's not doing it.
@@hermanhermitz9101 hi, ok, what about Perspex? That Should not trigger sensor by itself, right?
How to connect bell please share me
Thank you very much for the video
Thanks for showing
Graham R Dyer NP, ;)
Can you suggest how to improve its range to 4 to 10cm? If it is not possible with TTP223, what are the options?
According to the chip's datasheet, if the capacitor is replaced by a connection, a piece of wire for example, sensitivity increases. But if you use a capacitor, the manufacturer (Tontek) recommends a maximum of 50pF.
Спасибо!
Sir sentar ka output + ya -
Yes
Will this work through metal
No. See the datasheet. There can be only non-metalic surfaces in front of the touch pad on the PCB.
www.tontek.com.tw/download.asp?sn=475
No
How about you doing the same thing but with 5 of those sensors side by side operating any of them without interference with the others.
Yes i will do that because my Bluetooth speaker need 5 buttons in a row

The basic idea is clear, and this works across languages.
