Nitrogen/Phosphorus/kalium/Humidity/Temperature and PH Sensors

[subas]

Dear Admin.

Apologies there is a change in plan. please find the plan system that now required the sensors to be RS485 compatible, GPS data, and 4G LTE. Data obtained from RS485 Modbus is sent to the IOT cloud via 4G LTE together with GPS data so that that particular Sensor will be shown on Google Maps. Please see Plan.jpg diagram    

Need your advice on what is needed from your products that can help do all of this?

Regards
