IDS Intelligent Digital Sensors
The IDS sensors automatically store their unique serial number and calibration data. In addition, they also digitally process the measurement signal. The sensors can be moved from instrument to instrument and maintain their calibration data and transmit this information to the new instrument.
- Plug and play connectivity with each instrument
- IDS senors store their own unique ID with serial number and calibration data
- Digital sensor recognition, processing and data transfer

Climate change-driven volatility is changing lakes at the base of their food webs.
That’s one way to interpret new research that documented such a change in Muskegon Lake on the coast of Lake Michigan. Researchers found that, in one particularly rainy and cool year, normal phytoplankton diversity and patterns were cast aside. Instead, one group of algae dominated the entire year, offering a glimpse into the kinds of surprising changes that could happen in the future.
“Phytoplankton are a very responsive group of organisms,” said Jasmine Mancuso, whose research detailing the change in the lake was published in October in Journal of Great Lakes Research .Read More
While researchers all over the globe have been studying greenhouse gases, there are still some areas in the field that have not received as much attention as they deserve. Emily Stanley, professor in the department of integrative biology at the University of Wisconsin and principal investigator for North Temperate Lakes Long Term Ecological Research (NTL-LTER), has spent a significant part of her career exploring a few of them.
“Clearly we have a problem with greenhouse gases. What people may not realize is that streams and lakes are hotspots of global methane and CO2. Understanding greenhouse gas dynamics in these systems is important because they are vents all over the world and they are not insignificant,” said Stanley.Read More
Enormous amounts of excess nitrogen hit water bodies all over the globe, including the U.S., due to runoff from agricultural and other human activities. This nitrogen can cause dead zones and harmful algal growth. Before it reaches the ocean, microbes can process and remove some of it from stream sediments, connected aquifers and tidal freshwater zones. Thanks to this process, coasts can have a decreased likelihood of harmful algal blooms.
Keeping coastal waters clean is important for many reasons, including the fact that about 60% of the U.S. population lives on coasts. But despite the importance of these nitrogen processes, researchers have not fully investigated how they work.Read More
