some of the files for json is missing how to fix this

Hello, Thanks for the great video. I always thought it is necessary that the electrode (copper) touches the medium to work correctly So its okay if the electrode is completely sealed? Does this also work if i have tube in tube?

Can't make it work with Arduino UNO R4 WiFi

Is there any way to build a fightstick using a ESP32 S3 to be used wireless and wired? I mean, wireless using a battery (a powerbank) and wired when the battery goes empty.

immaculate tutorial, exactly what I was searching for, thank you

I wonder if that can work for other fluids.. probably is just individual kalibrering. Second question is how it will work if you have metal tankand glue it on a side?

Hey Kris, I'm wondering how easy it would be to use an ESP8266-E12 as opposed to an ESP 32. what changes would have to be made?

I want to ask- as depth increases, why capacitance is decreasing ? it should increase with depth right?

งงกับชื่อไทยเจ้าของช่อง แต่เสียงในคลิปเป็นฝรั่ง แต่ขอบคุณมากที่ทำคลิปดีๆให้ความรู้ครับ

hello sir can you help me to read data from PLC using esp32 and TT

Hi Kris, do you think it is possible to use this library for TP-Link Tapo P110 sockets too? I tryed it, but it only finds my KP105 which I don't want to control. I want to control the P110 energy meters

unfortunately it does not work on Wemos D1 mini (ESP8266)

Nice work Kris. Got it working on a ESP32-S2 with a HS100 plug.

bro can i do the same thing with Esp8266 ?

Sweet video!

Hello I'm new to this, I'm trying to learn. I see you connect B- and A+ from RS485 converter (yellow lines) to last 2 plc inputs (I suppose they are inputs). I do not understand how ESP can communicate with plc using 2 inputs..

Which language do you use to write the Serial monitor?Python, C++ or another?

hello may i know what software do u use to create the connection diagram? thank you

This looks very interesting. I'm just now getting into ESP32 and I'm liking it a lot. I have a question, however, about the lamination thing. Have you found that after 2 years, the lamination stays waterproof? Or has water seeped in?

Awesome demo! May I know what freq signal injected onto the copper pad?

Hi, can you give me this project? Im not so cool im programming, but i want to have my own recycle bin)

I am looking get your code working on my ESP32-S3 project, can you help. I've mostly programmed in Arduino, not Visual Study. Like you mushroom switches, funny!

Nice to have this library, but can it control Kasa Smart Strip?

rất hay , đã làm và thành công. Chúc kênh ngày càng phát triển

This is great! Where can i get the appropriate lwip library? Thank you!

hi kris,thank you for sharing amazing idea, but i have problem when build and flash the program, when im trying to flash it says "Variable ${config:idf.pythonBinPathWin} can not be resolved because setting 'idf.pythonBinPathWin' not found".what should i do?

ขอบคุณมากครับ

Great Video, i was wondering if it is possible to use the sensors with an RPI and without the ESP32 module. Do all the code in Python and connect the sensor to the GPIO Pins.

You LE3V manual says about P0-P63 pointers. Did you set it in Tool->Device/Label Automatic-Assign Settings Pointers? I has holding PLC on IF CASE operation and TON functional block without the setting.

Hello. I have the same FX3U clone. Could you help: what is the address map of Y-outputs throw Modbus( FX3U is slave) to read states? X-inputs and D-registers can be read directly (without M).

แล้วถ้าผมจะทำการ slaveตัว esp32ที่มีการวัดของเซนเซอร์ ให้เข้ากับ FX3U-14mr นี่ ต้องเขียนโค้ดเพื่อเชื่อมต่อตัว plcไหมครับ หรือเขียนแค่โค้ดของเซนเซอร์อย่างเดียว

Can you use an arduino uno microcontroller instead of esp32 and achieve similar results?

Great experiment. I'd like to build a water level sensor with this principie.

Hi Kris, thanks for the detailed and amazing tutorial. Do you think the sensor will still work well in salted or mineral water? or "grey water". I would like to apply this design to monitor the water level of a water garden

The Fx3u clone is the new Arduino on steroids. Affordable with so many documented projects. I got mine for $40

I couldn't wait to replicate your idea, Kris. I am impressed how well the thing works. I used 5mm stainless steel rods 50cm inserted into PVC pipes. The result is quite linear function. I am not friend with ESP-IDF, hence used Arduino. Each centimeter was around 1 point on the 0..50 scale.

Would it be possible to place the copper tape on the outside of an aquarium and have it function as a water level indicator?

Hi, can you give code of arduino ide platform

Which cable are you using to program the PLC?

Hello, thanks for the good example code. Have you tried other MCU, ie the RP2040 ?

To fix the problem with the measurement error (spikes) and also to get a higher resolution, simply call the function 'touch_pad_init ()' in the setup () routine.

Great project. I am looking for a way to measure level in a fuel tank. Do you think it is possible to replace the strips with a tube with a rod in senter? The tube will act as a capacitor. My plan is to immerse the tube into the tank. The tank is metal, and I can not use strips on the surface og tank to make the capacitor.

Hello, Thank you for the video. I have a question, I have no background in using this type of application. I am trying to use this as an FDC1004 contactless sensor because I cant get an FDC1004 at the moment, I only have the ESP32, do you think this will work? Thank you again.

ESP32 is Master?

Thank you, Kris, the experiences you so well shared in your video not only led me to making capacitive sensors with an iron on my desktop, but a way to achieve measuring soil moisture to provide water to maintain plants. I encountered difficulties with my python-version mess in the mac, so until I figure out the paths, I use a primary arduino code averagaing and mapping the readings (my equaly primary micropython dind't improve the readings that much), monitored wirlessly using virtuino. So, while I must hold to see the whole-grain stuff in my bowl, I found the sensors potentially functinal to operate a water supply sytem to a kitchen herb garden, so, I am much grateful to you for the spoonfull!

Thank you very much for sharing

I flashed the code on my wroom dev module. The Cereal Potter does not start at 600-700 and go down when touching the sensor. Mine starts at 0 and goes up to around 6 when touching either sensor. Any idea what's causing this?

I am working an project i have le3u 48mr plc i am devolping a programe temperature and pressure base control but these analog inputs are not enough for me i need 10nos analog inputs is there ant module i can connect with this plc

สวัสดี คุณยอดเยี่ยมมาก ฉันกำลังตรวจสอบอยู่มากแต่ให้ทำเช่นเดียวกัน แต่กับ Arduino เท่าที่ควร

Hi. How to change stop bit, parity, data lenght?
