Biospherical Instruments is delivering an array of micro sensors outside of their radiometer packages to provide more integration options through gas and hyperspectral sensing.
Gino IoT Micro Spectrometer
Gino is a miniature fiber optic spectrometer that utilizes nano-CMOS detection and a Czerny optical path to deliver highly precise spectral response data in a tiny package. It's embedded computer design allows it be a stand-alone product to fulfill a diverse range of scientific, industrial and agricultural applications.

MicroFlow Gas Spectrometers
These microflow sensors use NDIR detection technology to measure a variety of gas properties including carbon dioxide, methane and gas temperature levels. The compact, rugged sensors are conveniently compatible with the gas evaluation kit which has a modular design to monitor up to 4 gases at once.
