Temperature and Humidity Monitor Using ESP32 and Blynk IOT | Blynk 2.0 Projects

hi friends welcome direct friends in this video we can see how to mount up the temperature and humidity using esp32 and blink 2.0 let's get started [Music] the comments required for this experiment are esp32 board DHT 11 sensor connecting wires and connecting cable now let's connect the DHT 11 sensor with the esp32 board the hd11 sensor has three pins connect the positive pin to 3 volt in esp32 board and connect the outpin to pin number d27 and connect negative to ground pin foreign [Music] Now log into the blink.cloud website [Music] and go to templates page and click on new template here give any name for the template [Music] and I gave the name as temperature and humidity Monitor and select the board as esp32 and connection type as Wi-Fi now click on done now go to data streams here we need to create two data streams for temperature and humidity and create a virtual pin and give the name as temperature and virtual pin sv0 and data type as double and give the maximum value as 100 and give the unit as Celsius and click create now create the next virtual pin for humidity and select the virtual pins V1 and data type as double and maximum value as 100. and click create now go to web dashboard and drag two gauge widgets one for temperature and another one for humidity [Music] and go to settings and here also give the numbers temperature [Music] and select the virtual pin created for temperature now click save now similar like go to the gay second gauge and go to settings and give the name as humidity and choose the data stream as humidity now click save now again click save now we have created the template now go to the search option and click new device and click from template and here we can see the template which we created select the template and click create button now copy this template ID device name and authentication token and paste in our program foreign [Music] username and password and go to tools and select the board as esp32 esp32 Dove module and then select the port now click this arrow button and upload the program to the esp32 board now the program is uploaded and we can check the output in the web dashboard this is the output we can see in the web dashboard now download the blink up from the Play Store store now open the blink app and here we can see the template which we created from the blink dashboard [Music] now click on the template and now click setup dashboard [Music] now here we need to add two gauges one for temperature and another one for humidity now click on the gauge and here give the name as temperature [Music] and select the variable as temperature now go back and click on the second gauge and here give the name as humidity and also select the variable as humidity now go back [Music] and again click on the back button now we can see the temperature and humidity [Music] foreign [Music]
