Objectives
Data Acquisition Unit


A Real-time groundwater-level monitoring
network. Covering over 50 sites around Nebraska.
Provide fast and reliable data. Help
groundwater users to better plan for, recognize,
deal with, and document multiple-year
droughts. The network can be easily adapted to
other fields of environmental monitoring.
Water Monitoring Transducer Embedded System
The embedded system does preliminary signal
processing and packs the hydrologic data
collected by the transducer into a proper and
secure format ready for remote transmission.
Data Transfer Unit

Satellite Modem a Satellite Transceiver or
Integrated Cellular Communication Module
Both of these two communication methods
guarantee the reliable telecommunication with
minimum expense. The data acquisition unit
and the data transfer unit will be powered by a
solar panel and battery.
System Architecture

Data Processing Unit
GOES
Data Transfer Unit

The data processing unit, with a friendly
Graphical interface, will be developed to run on
the base station to display and archive the
real-time data.
Cellular Basestation
Data Processing Unit
The data processing unit will receive the
sensing data via Internet.
Pressure transducer
Data Acquisition Unit
This work is supported in part by USDA-RMA for
integrated Real-time Groundwater-Level
Monitoring Network for Support Drought Impact
