Next-generation sensors

Our technological choices and challenges in the development of in-situ and mobile sensors focused on achieving low energy consumption, providing embedded intelligence to transmit relevant and streamlined information, miniaturizing, reaching a low cost (at least a tenfold reduction), minimizing environmental impact, and ensuring social uptake (open source, accessible components, etc.).

Around twenty sensors are currently under development :

Surface dynamics

  • Hyperspectral camera to monitor surface state dynamics
  • Soil moisture sensor

Aquatic ecosystem fluxes and physico-chemistry

  • Multiparameter probe for the physico-chemistry of aquatic ecosystems
  • MOD probe
  • Radar 2.0 for real-time discharge measurements

Aquatic ecosystem metabolism

  • Proximity measurement station to study river metabolism (mini LOMOS 2.0)
  • Dissolved pCO₂ sensor
  • Mass spectrometer for high-frequency in-situ measurement of dissolved gases
  • Laser spectrometer for carbon isotope analysis

Contaminant dynamics

  • Contaminant accumulator in aquatic environments
  • Radon/gamma sensor
  • Caged and instrumented sentinel species

Greenhouse Gas (GHG) fluxes

  • Laser spectrometer for mapping and measuring GHG fluxes
  • Automated climate chamber

Animal behavior

  • Biologger for animal behavior analysis
  • GPS for tracking animal movements
  • Audio recorder to study animal behavior

Microbial activity at interfaces

  • Multiparameter probe for measuring biogeochemical activity in interstitial zones
  • ATP probe
  • Automated systems for high-frequency and high-resolution microbiological sample collection
  • Biogeophysical measurement device for biogeochemical activity in interstitial zones

Species richness and diversity

  • Audio-video traps for invertebrate and bird recognition
  • Semi-automated, broad-spectrum entomoscope
