Relatively inexpensive, transportable and deployable sensors are produced all over the world for a variety of analytes. Broadly defined, sensors respond to a physical or chemical property, providing an interpretable output. For our purposes, a main distinction of a sensor versus a sampler is that sensors do not require laboratory-based analyses, and provide outputs in near-real time.
