Accurate irradiance data is the backbone of solar project performance, bankability, and long–term investor confidence For EPCs, it shapes everything from yield assessments and energy modeling to commissioning acceptance tests and contractual guarantees. But this reliability depends on a critical assumption: the irradiance measurements used to validate performance are accurate. ...
Direct sunlight (straight from the sun) Diffuse light (scattered from the sky) Reflected light (from the ground or surroundings) Note: we shouldn’t mix between Diffuse light and DHI, because POA includes diffuse light, but not exactly the DHI measured on a flat surface, it’s the diffuse light as it falls onto the tilted panels.How is it measured? With a sensor mounted at the same ...
Technological enhancements in OGI sensors and cameras are at the forefront of these developments, with a specialized focus on refining capabilities for precise emission quantification. ...

Applications The application areas of the new color sensors are monitoring in the outlet of the sewage treatment plant and monitoring of surface waters . Methods The sensors measure according to the method DIN EN ISO 7887:2011, method C and according to the method APHA 2120 2018 (Hazen), method C. ...
Many interesting traits can be assessed with multi-spectral sensors, but many of the most exciting and impactful traits that leverage deep learning tools are extracted from imagery captured with high resolution RGB cameras. ...

This study introduces an instrument – the Spectral Intensity Bioaerosol Sensor (SIBS; Droplet Measurement Technologies (DMT), Longmont, CO, USA) – that resolves fluorescence spectra for single particles and thus promises to expand the scope of fluorescent PBAP quantification and classification. ...
About 43% of the works analyzed use multi-scale, multi-sensor, multi-spectral approaches for mapping degraded areas, with a combination of visual interpretation and advanced image processing techniques. The use of more expensive hyperspectral and/or very high spatial resolution sensors like AVIRIS, Hyperion, SPOT-5, and IKONOS tends to be limited ...
Abstract: A spectral in-situ UV sensor was investigated to measure nitrite and nitrate concentrations in the effluent of the EAWAG pilot-scale plant. The sensor was used with a calibration that was based on data from another WWTP and was operated over a period of 1.5 years. ...
