Development of PLC programming and remote communication by WIFI

Job ID: 31583738

Budget: $750 – $1,500 USD

My company has stations installed in remote sectors, all of them have Wi-Fi, via mobile broadband internet connection or satellite internet.
We must control and monitor a PLC with a step-by-step on and off programming. The variables to control are:
1 digital temperature sensor (on-off)
1 digital humidity sensor (On-off)
1 on-off switch
2 outputs
1 pulse output
The equipment works with 12V DC.
I need a reliable alternative that connects via Wi-Fi or network cable, but does not depend on a fixed IP. We are flexible in the PLC model
