Introduction to Sensors for the Aquatic Environment
A sensor is a device that responds to a certain parameter by producing a repeatable signal that can be read and interpreted by an observer or electronic equipment. Sensors are used in the context of lake science to measure many environmental characteristics that may assist in drawing conclusions about water quality and ecologically important parameters. Sensors are generally categorized by what kind of parameter they measure. A sensor can measure physical, chemical, or biological qualities of water, or they can assess the surrounding meteorological conditions. To learn more about the common types of sensors and how they work, follow the links below:
While it is easy to separate sensors by the types of parameters they measure, they are often combined into multi-sensor units to develop a more complete picture of how parameters interact and how lake ecosystems function (Figure 1).
