Intro: Arduino Webservers Ethernet ENC28J60 With Thermometer DS18B20, I2C LCD and Power Over Ethernet POE for ZABBIX IOT Data Logging

Low-cost Arduino Ethernet webservers are reliable for different sensor monitoring: temperature, voltage or switches. In a pdf file is a description for Arduino webserver powered via the 5V USB connector or using Power Over Ethernet (POE).

Data can be fetched from Arduino Webserver webpage for example with ZABBIX that is a platform for IOT signal monitoring developed for server room monitoring and for sending out alarms. It is similar to Xively, but ZABBIX provides installation download free of charge http://www.zabbix.com

Power over Ethernet was a tricky thing to achieve. Ethernet connector of ENC28J60 shield has a transformer inside that galvanically separates inputs from outputs. To get POE the metal shield of the connector was cut off with a diamond disk allowing to solder wires to the connections before the transformer.

Attached pdf file contains description how to build versions without or with LCD screen.

It looks neat :) If you would like to break down the steps into written instructions and add some progress/step photos so that others can replicate your projects then it will receive more attention from the community and be possible to be featured on the site. https://www.instructables.com/id/How-to-Create-a-Fe...

I had previously a not too positive experience with multi-step instruction because after years the layout changes, some files can disappear, commercials get inserted, etc. So I prefer to stay with fixed pdf version.

I could not compile Zabbuino with DHCP enabled as some error appeared that I had no clue how to go around it. It is too complex solution.
