Awsom video.... can you do one that uses a OLED Display?

[fawad]

Can we connect M5STACK-CORE2-ESP32 with the DHT 22 the same way as you did in the above video?

[tomalchowdhury]

Sir your video is so helpful for using arduino. Please make video on 7 segment or matrix display with neopixel ws2812b.

[londam]

Hi, great video. Could this be used to periodically (say once per minute) log the data (temperature and humidity) to some kind of spreadsheet (googlesheet) to track the change of values in a graph?

[gash]

Hi,
Great video. Need some help.
I'm trying to go to the IP address and see the readings, but I get just the humidity information. I need both temperature and humidity to be seen. Can you help with that please?

[gorkaalonso]

Thanks for sharing your incredible knowledge, you make it clear and easy. I'm trying to reproduce your project by adding 3 more DHT22. I'm not getting trusted values since I'm using the same ESP32. Do I need to get 3 of them and link it to a main board? Thank you for any further information. keep it going

[smartassist]

If below correct. How can I have results BOTHshow on monitor (and write to a file). I need to print file results for 120 days. (I should be able to change intervals to every 4hrs to test and record results). Can HOMEASSISTANT (HASSIO) allow me to record 120 days of report to print?

[hofertyp]

Great Video Ahmat thank you. Seems like you are from Afghanistan? I'm using a ESP32 Cam with it's own Webserver. Is it possible to add your Code also and have two Webserver on one Esp32 cam module?

[skyboy]

Why do you disconnect the power wires for the sensor when uploading the code? If this were soldered together, you could not do that so I wonder why you do. Thanks!

Bonjour
Merci pour cette vidéo
Svp comment peut on faire pour récupérer les données du moniteur série pour les enregistrées dans un ficher de sa machine ?

Est il possible de faire un montage entre un esp32, une carte arduino et un capteur dht22? Si ou comment svp ?

[-Ramani-gozq]

Sir can we have sensor to measure the temperature values for deliveries.. please help this is my final year project

[kslim]

Can I use a OLED display with the ESP32 to display the temp and humidity also with the web

[timraz]

Am I able to use the same code on the esp8266 instead of the esp32 ?

[kslim]

I actually meant was it possible for me to setup an OLED with the current configuration to display what was shown on the web, this way OLED would be local for me to see in the room... and the browser for when I'm sitting at my desk on the same network 🙃

[feyyazsandkc]

Hello ı have some problems. I did everything like you but it doesn’t define an IP adress. It constantly prints “…..” How can I fix it ?

[UpSpider]

Anyway to store data in a graph or to monitor the temperature when you are not connected to the same WiFi network? Something like a VPN I guess

[smartassist]

How much cost to set up my 6 devices with battery power each?

[josephchan]

How can I get the code for esp32 control pca9685 16 servers use smart phone?

[smartassist]

So DHT BLUE IS FOR HUMIDITY / DHT22IS FOR TEMPERATURE. AND A SINGLE ESP32. THEN WE GET BOTH TEMP AND HUMIDITY.
