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

About: I am a researcher leading quantum optics labiratory. Previously I was working on development of optical atomic clocks. Electronics is my hobby since childhood when my uncle was bringing me old phones to play a…

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

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.
