Thanks to Evengy Levkov,

I made some modifications in the code , made it more basics , this was tested with arduino uno and
5100 ethernet shield.

here the source :

In Zabbix just do the following ;

  1. configure a host with ip address of the sketch example arduino3 with ip 192.168.1.93
  2. configure you're items like following
    Host arduino3
    Description Temperature sensor1
    Type zabbix agent
    Key sensor1 // as in the sketch
    Type of information numeric float

Have fun
