Hello,

It looks like the code you provided is incomplete. However, I can give you a basic concept of how the code can be updated to display the temperature measurement from the DS18B20 sensor on the OLED display and send the data to the Blynk application.

I assume you are using libraries that support the ESP8266 module, DS18B20 sensor, OLED display and Blynk.

Below is sample code that shows how to do what you are describing:




Assuming the DS18B20 sensor is connected to pin D2 on the ESP8266 board, this code will read the temperature from the DS18B20 sensor, display it on the OLED display, and then send it to the Blynk application.

Substitute "YourAuthToken", "YourNetworkName" and "YourPassword" with your Blynk token, Wi-Fi network name and password.

This code is fairly simple and does not include error handling, so you will probably want to extend it to better suit your needs.

Please note that you will need to install the required libraries in the Arduino IDE environment. These libraries are: Adafruit_GFX, Adafruit_SSD1306, OneWire, DallasTemperature, ESP8266WiFi, BlynkSimpleEsp8266.

Hope this helps! If you have any questions, feel free to ask.
