You can use an Arduino Uno WiFi board to create sensors that are web accessible. This project allows you to read the temperature through a web browser.

Note: I found that the 5V pin on my Arduino Uno WiFi only actually outputs 4.85V. This means the temperature readings are off by about 5 degrees. Make sure to verify your project is reading the correct temperature, and if not tweak the math as need be.
