i don't understand how this type of videos have less views that trash videos , excellent thanks :)

One of the best video tutorial I have ever seen. Well done!

Very good, thanks. I made a remix with your ideia in this video and with the Oled display, now I have a system that shows the temperature in all devices connected in this IP and in the Oled, as the same time. Thank you for shared your knowledge.

Just awesome explanation! Thank you!

I love the detailed voice-over explaination.👍👍

Bro your tutorials are soo amazing good! Never seen anything like this before on youtube ! Ty soo much :)))

Great job Rui, I'm definitely going to upgrade my current weatherstation as fast as possible. I'am wondering if it is possible to draw diagramms with the sensor data to see for examle how the temperature has changed over night. It would also be nice if you could display the lowest and highest temperature per day on the website. ;)

Thx mate, this was so useful for me!

Excellent tutorial. Thanks very much for sharing!

EXCELENT..!!!..., thanks for sharing and the mailing list

Thanks, this video helped me a lot :)

Thanks for the informative video. I'm trying to make an arduino that monitors humidity and temperature in my mushroom fruiting chamber. I'd like to use the data from these sensors to also create a graph. Any tips?

Great Rui !!! ... But, I didn't understand the lower part of the web page, how did you replace the variables in HTML with the sensor readings ? "using the % symbol" ?

Great video, thanks!

Grato por compartilhar conhecimento! Trabalho muito bem elaborado, aprendi muito.

thank you so much bro u saved me from a lot of researches from google

Can you please make a video on ESP32CAM to send files over Bluetooth considering Aithinker's builtin Bluetooth. Thanks

Awesome tutorial, i subscribed immidiately :)

Grato por compartilhar conhecimento Rui. (Had to look that one up) Great video. Can i use basicaly the same method with a max31865 rtd converter and a rtd100/1000 sensor? Witch library would i need then?

Awesome tutorial. Is it possible to have a control of this module and have the data from this station show up in homeassistant iot interface. Thx

Thank you so much for this video. Very good.

great video tutorial. i have a question though regarding about this esp32. im building a project that will need a camera and internet connectivity and found that there is a esp32 wifi camera. my question is if the esp32 wifi camera can be used to control the arduino over wifi while receiving data then send it to an android app

Hi Am I able to print a series of texts (from data from a flex sensor - for eg. “hello, how are you?” onto the webserver that the esp32 connects to?

Thanks for this project and tutorial it has come in really handy. Is it posible to integrate an email alert if the senor detects a dip or increase in temperature? Email would be from pop3 /smtp. Thanks again!

Nice man! im currently building smart terarium and this is exactly what i need. Previosly i was using html meta refresh command and after 30mins my esp always soft WDT resets.. Could this fix it? or do you thing my app crashes for some other reasons? because when i dont have the web interface opened it runs smoothly :D

I just want to ask about the esp32, I have a problem when uploading the codes to the esp32. Some says ur need capacitor 10uf to connect the gnd to the EN pin. i dont remmber.. but somewhere in the esp32.

the Webserver can monitor the temparature and humidity value on runtime ? we don't reload website to update the value? Thanks for this interesting video. So very useful!

eXCELENT! How can I do the same but with 4 sensors (4 esp32) I need all of them shows on same page...

The DHT22 sensor enables temperature measurement in the range of -40 to 80°Celsius Does your program accept this? I.e it also shows negative temperatures?

Hello, great work, thanks. But i ran into an issue: If a add more paragraphs for other sensors, the last paragraphs on the page wont be displayed…doesnt matter what i put on the button of the page. Can you helb me?

If i use the AP mode instead of a STA mode will the values still get updated . And how exactly is the values getting updated automatically without actually using AJAX or anything else without actually refreshing the page ?

Antes demais parabens pelo bom trabalho e por partilhar, tenho uma questao, e possivel atribuir um ip fixo ao esp 8266 para nao estar a ser atribuido pelo dhcp?

Hello,Nice tutorial! How can i use for a hc-sr04 sensor?

Very good thanks.

how can i add more sensors to the system? I did try but I can't upload the data from the extra sensor onto the web page? can you help me?

i want send a voltage of a potentiometer to a web page like you, you use a library for the sensor, i dont know how make that., can you hep me?

if you have multiple sensor, is it possible to write something like this DHT garden[2]; then you could initialize them in a for loop like for (i=0; i

Sir how can i send a message with valiable data from android using MIT app to the esp web server? How the esp can get that data? What i mean is like for controlling led brightness

You are my god

thank you

Rui Santos, I have problem "Error compiling for board ESP 32 Dev Module" please i need solution

How could I change the background color of the web page according to value of the Temperature ?????

is it possible to use 2 sensors(dht22) in 1 esp32?

how i make that with fix IP? for example 192.10.1.1 then i login in with that ip? Thank you from Greece

Great vidéo thanks. i tried to do the same but the page would not referech automaticly anny help please !!!

Hi Rui! Great video, ¿can you make a video with ESP8266? Thanks.

Muito bom este vídeo, muito bem explicado só é pena não ser em português.

It is possible to have fixed website name instead of IP address? Is Arduino library capable of that?

Hi I have IDE 1.8 arduino esp 32 dev the code stops at the WiFi.mode! the mode is not highlighted cant load any idea what the problem I have used this tutorial before no problems thank you

When connect serial cable with esp32 on rx pin WiFi of esp32 not working it disconnected I take data from. Weights scale and send ko webserver using esp32

im trying to run this on a nodemcu esp8266MOD, and first i was getting an error about the conts ssid, if i chnage it to insert my ssid and password instead of variable, then the error im getting is Error compiling for board NodeMCU 1.0 (ESP-12E Module). can anyone offer some advice please?

Friend you could do this same project with local indication with Oled display 0.96 I2c SSD1306

Very Good, How to Access this IP outside wifi? from the mobile location? Any Help!!

Amazing

Can you do it as an access point?

i want to build web server using arduino uno. is this possible? can you help me out with it

Thanks for sharing such an Awesome project. Can I get the same web page over an access point without having local WiFi network. Awaiting your earliest response. Thanks.

Hi. Thx for this titorial. I need control 4 buttons/relay also. What is the best node to abord this?

Can you make update? Temperature and humanity graph?

Can I see this output only ip address? And how to store pc? Please help

How do you know what board to use?

thank you, good job. I have tried according to the tutorial, but why is it slow response from esp32 sometimes it doesn't even respond

Iam trying to do same from last 1 week still cannot can help me how to connect to you

Hi, my name is Eric (new subcriber) I have a projet of "connected beehive" to monitor the weight (HX-711 analogic sensor) and temperature (DHT22 digital sensor) with an Heltec ESP 32 Lora V3 board. I'm working with IDE Arduino interface and the driver of my Heltec V3 board has been successfuly installed as well as the boardmanager and library so that the COM communication between my Arduino IDE and my Heltec board works normally. My Heltec board is poorly documented (only a pin diagram which speaks more or less for me) so I found your channel with several videos dealing with "ESP32-DHT" ... But I have problems to make work (simple) sensor such as my DHT22 with my board. I mean I get "abnormal results" from my DHT22 sensor, such as T=253°C and H=253% (let me add that the problem doesn't seem to come from the sensor because I also have a DHT11 which gives the same abnormal results) These abnormal results I got from my DHT22 sensor with my Heltek ESP32 V3 board occurred with the "basic" example you gave to monitor a DHT 22 sensor on the serial monitor of an IDE Arduino interface. As a matter of fact, i exactly used the connexion example you gave BUT for the data pin, I replaced the GPIO 27 (digital pin of your ESP 32 board) given in your example by the GPIO 46 of my Heltec V3 board (which should be a digital pin if I'm not mistaken but I would like you to confirm if you can) After this first problem of abnormal results of my DHT 22, I decided to "start again from scratch" with another of your examples (i.e. the present video dealind with "ESP 32 and asynchronous web servor") BUT I faced with another problem when I downloaded the "DHT unified sensor" library because I wasn't able to make any modification of the sketch because of a error message ("cannot edit in read-only editor") Then I opened the "preferences" of the IDE Arduino interface but didn't find any option to enable the edition of you "DHT unified sensor". So I have 2 questions: 1) how to enable the "edit mode" of your "DHT unified sensor" sketch so as to change the pin name and DHT sensor type? 2) could you confirm that the GPIO 46 of the Heltec ESP32 Lora V3 board is effectively a "digital" pin which suits for the connexion of the DHT22?

nice! thank you. just one question, how to run any dht in web server with nodemcu or esp32?

Hello. Thank you for your great work. How to add button for LED in this script?

What is the range of it??

Hello Rui, I have been successful to replicate your ESP32 DHT11/DHT22 Asynchronous Web Server project, with the info in your great video. How can I convert the sketch to make the ESP32 modile an AccessPoint to communicate with my iPad as a WiFi client. My project will not have access to cell communication or internet access; such the need to make the ESP32 an access point to communicate data.

Does it need internet to transfer that data

how can we make the IP static?

Xin chào bạn. tôi ở việt nam . tôi đã làm được. cảm ơn

Hola, una pregunta, con el esp32, cómo se puede configurar en modo (Accesa point) y de Cliente. Y como con esto puedo generar una red de esp32, gracias

hey, i have this error message: error: unterminated raw string const char index_html[] PROGMEM = R"rawliteral( ^

Where to get this ip address ?

I am trying to connect dht22 to esp32. But esp32 gpio can only tolerate 3.3v whereas dht22 output is 5v. How do you solve it?

It is possible instead using the local ip ( 192.168.0.1 ) to use a domain that can be accessed over internet ?

Hi

its not IoT right? its work only in local network?

hello~ I am trying this project,but when it complied ,the arduino ide said that no such file ... If you ever change the the file's name of AsyncTCP?

ok, now i'm confused, "Rui Santos" sounds like a Brazilian name ( I'm brazilian), but boy ur accent sounds like russian... MISTER RUI I DEMAND EXPLANATIONS! TRIRTY TUE is russian accent!! you cannot fool me, you are a spy!!

hey can i add this with my arduino uno board?

Friend you could do this same project with local indication with Oled display 0.96 I2c SSD1306
