Résumé
This publication aims to describe a new low cost, compact, autonomous, and multi-sensors instrument developed to measure in situ bioluminescence: Biosealight.
The sensor's acquisition system is built around a highsensitivity photon detector that detects photons and converts their number into proportional electrical signals. The photon detection system is integrated with additional sensors that record environmental, including pressure (rated up to 600 bar), temperature, and various system voltages. These measurements are managed by a motherboard featuring an STM32 microcontroller.
By proposing another way to measure the bioluminescence in situ, and being easy to deploy, this instrument will increase the capacity to observe and charaterize bioluminescence of organisms and improve our understanding of its ecological role.
