AquaMon® System Configuration
System Configurations:
The table below illustrates how different configurations of AquaMon support a wide variety of agricultural needs.
This is just a sample of AquaMon’s flexibility.
If you need to monitor or control something not described here, contact Cermetek and we will help identify the sensors and/or actuators needed to support it, and integrate them with the AquaMon hardware sensor interface and configure the RSVP software to support the sensor.

1 Either the irrigation line pressure or the soil moisture level may be used to indicate the last application of water for CWSI calculations. On the LeafMon the user may also enter the last irrigation time manually.
2 The RS485 Interface allows proprietary communications with an appropriately equipped AquaMon System.
3 The LeafMon-S is schedule for release spring 2016.
