Updated: Jul 2, 2021

In this tutorial we will show how to build ESP8266 and interface DS18B20 temperature sensor and LCD display. This project uses ESP8266 NodeMCU device that easily connects to existing WiFi network & creates a Web Server. When any connected device accesses this web server, ESP8266 reads in temperature from DS18B20 Temperature sensors & sends it to the web browser.
