Vision Research has introduced high-speed cameras capable of capturing images in the extended light spectrum of UV, visible, and Near-IR wavelengths. The cameras have over 70% Quantum Efficiency (QE) at 300nm, as well as unprecedented QE at other points of the UV light spectrum, allowing researchers to potentially capture images using just the camera and […]

FAQ on railroad hot-box-temperature sensing: part 2
Modern electronics should be able to easily solve a temperature-sensing challenge, but the harsh real-world complexities make it a difficult proposition. Part 1 of this article looked at the basic issues of railway bearing failure and detecting these before they happen. This part looks into more details and sensing options. Q: What can the railroad […]
How can sensors protect vulnerable areas? Pt 2
Part 1 of this four-part blog addressed air quality monitoring in cities and populated areas. Less densely populated areas such as a rain forest may require different approaches. In addition, water quality monitoring in outdoor locations as well as clean drinking water from processing stations provide additional sensing opportunities. Part 2 will address these areas. […]
IoT light sensors measure either ambient or UV light
L-com recently announced the expansion of its line of IoT light-detection environmental sensors. The sensors gauge either ambient or ultraviolet light. The new sensors assist in the use of IoT data collection to make process control more efficient and lower building and process costs. Applications for light-detection sensors include greenhouses, agriculture, solar farms, labs, factory floors, manufacturing, […]
What is the difference between sensors for low UV, middle UV, and UV-C light?
Unlike visible light, which ranges between 380 nm and 780 nm, ultraviolet (UV) light wavelengths measure between 100 nm to 400 nm. UV is broken into subcategories known as UVA, UVB, or UVC. While UVC rays are the shortest and strongest, naturally occurring UVC rays are mostly absorbed by the atmospheric ozone layer, so they […]
How can sensing protect art and priceless artifacts?
Ultraviolet (UV) light, illuminance, temperature and humidity are all very harmful factors in a museum or an archival institution. These factors can all negatively affect the quality and longevity of a piece of art or artifact if the piece is exposed to extremes for too long. Data loggers that measure/monitor critical parameters and communicate with […]
ICs for Environmental Sensing
At Sensors Expo 2016, John Geis from IDT explains an environmental sensor demo board with gas, temperature and ultraviolet sensing. For more information, click here.
