Smart Geo Particle

Description: The “Smart Geo Particle” (SGP) is a small river drifter developed by the Centre for Biorobotics at Tallinn University of Technology. The SGP is an IoT device that can provide real time estimates of position, travel speed, accelerations, orientations or magnetic fields using a mobile communication at 1 Hz as well as on board recording at 5-10 Hz. These properties make the drifter an ideal tool for the instantaneous characterization of small to large river streams.

o Flow classification
o River studies
o Flow velocity, acceleration, mapping


Description: Homer is the first artificial lateral line probe, built and tested during the EU BONUS FishView project. It consists of an array of pressure sensors and two in-line linear accelerometers, recording data at up to 2,500 Hz. It has been successfully applied in the lab and in the field to estimate time-averaged flow velocity, turbulence as well as autonomous classification of real-world flows in vertical slot fishways.
Key features:
o Pressure sensing artificial lateral line and linear accelerometers
o Useful for both laboratory and field measurements

Prototype of BDS

Barotrauma Detection System

Description: The Barotrauma Detection System (BDS) sensors are fault-tolerant sensors capable of travelling through hydropower turbines.
