Senix AirWire Local LoRa Tracks River Data Alongside USGS Monitoring
Since 2001, the United States Geological Survey (USGS) has collected water-resources data in all 50 states and beyond. The organization has studied groundwater, surface water, water quality and water use through initiatives such as the National Streamflow Information Program (NSIP), which used to be known as Federal Priority Streamgages (FPS) program.
There are five goals that guide NSIP planning, one of which is data collection for future planning. Per the USGS website (https://water.usgs.gov/nsip/goals9.html):
The NSIP plan calls for intensive data collection during major floods and droughts. This additional information is needed to provide improved estimates of risk and impacts for better hazard response and mitigation.
Municipalities around the globe are learning firsthand that proper planning for flood events can help to bring about substantial improvements in protecting lives, property, and ecosystems. Data collection is a critically important tool in these efforts. Access to good data will lead to smarter land management decisions.
Senix Corporation of Hinesburg, Vermont, offers ultrasonic sensor-based monitoring systems that can help collect this valuable waterway data, called the AirWire Local LoRa system. The tool collecting the data is the Senix ToughSonic ultrasonic distance and level sensors. These tough, durable devices are housed in 316 stainless steel with fully potted electronics (rated IP68) to withstand harsh outdoor conditions for many years of reliable service in the field. The sensor data is then securely transmitted via Senix AirWire technology using efficient LoRaWAN technology.
The AirWire LoRa Transmitter Box connects to any Senix brand ToughSonic General Purpose or CHEM sensor. The Transmitter Box contains 3 D-cell alkaline batteries, which provides power to both the sensor and the LoRa Radio Transmitter. Logic in the Transmitter Box instructs the sensor when to ‘wake up’ at user defined intervals to capture measurements. The data is then sent via spread spectrum modulation over sub-gigahertz radio frequency bands to a nearby powered LoRa Receiver/Gateway device that displays the sensor output and can also be configured for data logging.
