About Calumino

We are shaping tomorrow with intelligent thermal sensing.

About Us

The energy of heat and light is essential for human existence. The name CALUMINO draws from this inspiration as a portmanteau of CALorie (the energy associated with heat rise) and LUMINOsity (the radiated electromagnetic power of light). 

Thermal imaging sensors offer a unique lens to our world by sensing heat signatures. When combined with computer vision AI technology, thermal sensors have the power to revolutionize how we manage, monitor, and secure our living and working environments.

Calumino is on a mission to unlock the potential of thermal sensing technology and help propel industries forward by delivering new levels of insight and control for businesses. Having pioneered the world’s first high-performance, affordable thermal sensor, Calumino’s technology is introducing intelligent sensing to a broad range of new industries.
