Overview
The Onsite 12-bit 4-20 mA Input Adapter interfaces with any sensor and provides a 4-20 mA signal to connect to smart sensor-compatible HOBO stations. This adapter features both a non-switched input and a battery-saving switched input that extends the life of external batteries. It also provides a trigger signal for controlling power to attached external sensors while offering digital filtering, which improves measurement accuracy with 32 readings/sample and 60 Hz noise rejection.
Benefits
- 12-bit resolution
- Digital filtering improves measurement accuracy with 32 readings/sample—4-• 20 mA adapter has 60 Hz noise rejection
- Measurement averaging over logging interval further enhances accuracy
- Plug-in modular connector for easy interface with HOBO stations
- Screw terminal for connecting to sensors
- HOBO RX3000 and U30 stations have room for two adapters
- Use with HOBO USB Micro Station and HOBO MicroRX Station requires Smart Sensor Consolidator Box (S-ADAPT-6) and an extension cable
- Represents one data input channel

Great Lakes Research Center: Designing Targeted Monitoring Solutions
According to the National Oceanic and Atmospheric Administration ( NOAA ), the Great Lakes have more miles of coastline than the contiguous Atlantic and Pacific coasts combined and contain 20 percent of the world's freshwater, making it a critical region to protect and conserve. Continuous monitoring and data-informed resource management are key components of managing waters in the region. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs and deploys monitoring platforms throughout the Great Lakes. With a background in environmental engineering, Henderson enjoyed the challenge of creating systems and making them work to obtain difficult, remote measurements.

Monitoring Meadowbrook Creek: Real-Time Data Collection in an Urban Creek
Meadowbrook Creek in Syracuse, New York, has been monitored by Syracuse University (SU) faculty and students for over a decade. Originally established by Dr. Laura Lautz in 2012, the early years of the program focused on collecting grab water samples for laboratory analysis and evaluating the impact of urban land use, human activities, and natural processes on water resources. Tao Wen , an Assistant Professor in SU’s Department of Earth and Environmental Sciences, took over the program in 2020 and upgraded the existing systems to include 4G modems that allowed for real-time data viewing.

Lancaster County Makes the Switch to Real-Time Water Quality Monitoring Systems
Continuous data collection in Lancaster County, Pennsylvania, started about 5 years ago, and the county will be making a major upgrade over the next year—switching from relying solely on the internal storage of water quality sondes to telemetry units that enable real-time data viewing. [caption id="attachment_39295" align="alignnone" width="940"] The first telemetry unit was installed at LCCD along Little Conestoga Creek.
