Concept Details

  • Specifically developed for measurement in confined environments that are not accessible during the measurement
  • In principle the same spectral characteristics and calibration models as the handheld sensors
  • One or multiple borosilicate glass windows with tailored spectral sensor units
  • Sensor balls use Compolytics’ proprietary Green Sensing technology
  • Powered by onboard batteries, the sensors are designed to operate for extended periods without recharging
  • Data transmission via radio technology in the short and medium range, e.g., BT-LE, WiFi, LPWA
  • Fully waterproof, airtight, and floating; the resulting physical density is aligned with the density of the environment, usually a liquid medium, to ensure that the sensor is neither strongly buoyant and only floats on the surface, nor settles to the bottom
  • The sensor ball follows the natural movement of the surrounding medium, e.g., flowing with currents or responding to mechanical stirring
  • Integrates physics-aware machine learning models to analyse fluid dynamics and environmental conditions surrounding the sensor ball, enhancing its core sensor data
  • Multiple sensor balls can be combined to a sensor swarm
  • Explored for use in Earth observation, industry-scale continuous stirred tank reactors (CSTRs) in food processing, and beyond
