ESP8266 Web Server Based LM35 Temperature Data Logger

In this tutorial we will show how to build ESP8266 and interface LM35 Precision Centigrade Temperature sensor with html gauge, data plotter with logger. 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 LM35 Temperature sensors & sends it to the web browser. In this project temperature range reads trimmed from 0°C to 100°C (Actual -55°C to 150°C). Here High chart is used to create reliable and secure data visualizations and data logger. You can export the data to CSV, EXCEL format and graph convert to PNG,JPEG,PDF format. www.dofbot.com/post/esp8266-web-server-based-lm35-…
