Please note that the DHT11 will not read temperatures below 0 Celsius. DHT22 will but there are many counterfeit ones on the market that seem to have a DHT11 instead. If you do need to read those lower temperature a Dallas temperature sensor like DS18B20 will be a better choice but will require different programming. I use a (counterfeit) DHT22 plus a DS18B20 so I get the temperature from the DS18B20 and the humidity from the DHT22.

Your vídeo is so good, thanks, you gived me the opportunity to end my project, i appreciate.
A serial exception error occurred: Write timeout Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
I have already installed DHT22 library but it will just showing me the error directory has not found something something could pls help me with this sir
Unfortunalty, now (early 2025), Blynk restricted the free use. Only 30K "messages". The free account will be exhausted in about one hour and is reset only after 30 days. To save the transmitted data, you should change the timer.setInterval at least at 10000L (reading transmitted every 10 sec.)
Brazil 🤝 You

sir, can we connect only multiple sensor in esp32 and where should we connect it ?
I did this but temperature and humidity display as 0?.What should i do.?
Check the circuit connection
how to do this with breadboard please
Showing error BlynkSimpleEsp32.h no such file or dictionary installed ardino esp32 packages but it is showing the same error
Install the Blynk Library.

Hi my device is online in Blynk but it doesn't show the values for Temp and Humidity
Please check the connection.
it is coming that DHT.h: No such file or directory while uploading program what to do pls tell
Please install the DHT library from Tools -> Manage Libraries
@@TechTrendsShameer ok, thank you.

How to measure current with ESP32 Blynk and ACS712 Current Sensor?
it worked, thank you!!
You're welcome!
Bro i am using esp8266 is it working for that and it not produce any wifi
Please help 🙏🙏
I didn't understand your question. Please explain.
sir, in blynk app, it is showing status as offline. how to solve this.

Main is #include
Thanks! 💪
Is it work
@@smaruyczymsstudio8491 which DHT Library did you use?
sir how to display float values on blynk app display
Select data type as double in Blynk Datastream
@@TechTrendsShameer I have selected double but it is showing as integer value
Can you please give workflow diagram for this
Failed to read from DHT sensor
Check the circuit connection and make sure there is no contact in the wires.
am i should put my ssid wifi and pass in the program?
Yep
Where is the program
When I upload the code it show error
Send me the error message.
@@TechTrendsShameer how...
