Center for Embedded Network Sensing (CENS) is a research program that helps scientists learn more about their environment and how to monitor it. CENS uses special sensors, computers, and other technology to gather data from the environment around us. CENS sensors measure things like air and water quality, temperature, humidity, light, sound, and other things that help scientists learn more about what is happening in our natural and built environment. With the data collected by CENS, scientists can make decisions that help us better understand and protect our environment.
