Scientists from the University of Rochester and UC Santa Barbara have built a laser so small it can sit on a penny. But don’t ...

[John Crombie] had a crack at building one using linear Hall effect sensors and magnets as the ... [John] utilises the Arduino pro micro for its copious analog inputs and USB functionality.

Considering the CG-PGB structure inscribed in the G-CLC film, we then demonstrate the local position-dependent tuning of laser emission. Figure 9b shows the microscopic reflection (upper ...

As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP30 provides more detailed information about the air quality. Download all the source files and open examples ...

Abstract: The fabrication, characterization, and gas sensor application of a hollow core photonic bandgap fiber (HC-PBGF) with laser drilled lateral microchannels will be described. The HC-PBGF was ...

Abstract: In this letter, a temperature sensor based on a fiber ring laser with a reflective Sagnac loop is proposed. The reflective Sagnac loop inserted into the fiber ring laser through a download ...

This is an Arduino library for SDI-12 communication with a wide variety of environmental sensors. It provides a general software solution, without requiring any additional hardware, to implement the ...

With the advent of a quantum cascade laser with emission frequencies specifically tailored to efficiently overlap benzene absorption as the most relevant analyte, the overall sensor footprint could be ...

Herein, we introduce a transcutaneous, continuous multianalyte sensor referred to as the PALS (Figure 1A).PALS employs two unique sensing modalities at the tip of a transcutaneous multianalyte sensing ...
