Data loggers from Campbell Scientific incorporated in ALERT stations deliver versatile functionality extending beyond flood warning duties.

ALERT stations are typically set up to acquire and transmit hydrological and meteorological data on a time and event basis. Networks using the ALERT protocol are designed to give immediate access to data that indicates the likelihood of flood conditions. The capabilities of Campbell Scientific’s CR1000 measurement and control data loggers in the ALERT stations however, can be leveraged to perform a variety of services including delivering road weather data.

Douglas County, Colorado, in conjunction with Denver’s Urban Drainage Flood Control District (UDFCD), operates an extensive ALERT network to monitor potential flood conditions. In 2008, the county decided to include additional capabilities to the next ALERT station to facilitate a complete road weather information system (RWIS). This set-up would include a camera to monitor stream and road conditions, and a road temperature sensor to aid the Public Works department with winter maintenance.

Water & Earth Technologies of Fort Collins, Colorado worked with Campbell Scientific to design and build a new multipurpose system, which not only provided the immediacy of an ALERT station but also offered real-time and historical weather data for meteorologists. The system also included a cellular router for remote data access and transmission to the Weather Underground (WU) site (wunderground.com) in addition to a camera to send images to WU as well as the Public Works department.

Campbell Scientific’s CR1000 measurement and control data logger was programmed to instruct the RF500M radio modem to transmit precipitation, water level, wind speed and gust, wind direction, and battery voltage to the UDFCD base station in Denver using the ALERT protocol to provide flood warning.

Additionally, the CR1000 data logger functions as a web server, using cellular communications to provide other users with near-real-time images of the stream, along with the same type of data sent to the ALERT network as well as temperatures for water, air and road surface. A staff gauge painted on one of the bridge piers to be visible by the camera is used to verify the performance of the water-level sensors.

The CR1000 data logger is also configured to send current data and camera images to Weather Underground.

Since the ALERT stations rely solely on solar power, the CR1000 can be programmed for power-saving techniques such as turning off the camera at night and powering down hungry sensors when they are not needed.

CR1000 measurement and control data loggers are available in Australia from Campbell Scientific Australia .
