Technology

The Modular Sensing Ultra (MS Ultra) can be used to monitor water levels in a wide range of applications, including rivers, lakes, dams, fishways, tidal areas, and groundwater. The device is easily configurable without needing external applications by standard USB connection. MS Ultra can work standalone as an autonomous independent sensing platform or inside a sensor network, thanks to the on-board LoRa module. This sensor features a high precision ultrasound sensor, solar panel and electronics embedded in durable IP68 ABS housing. The programmable recording time provides an ideal solution for long time recording of water level. Moreover, its architecture makes easy to incorporate other environmental sensor (temperature -air or water-, humidity, barometric pressure, etc.).

User guide Software

The Modular Sensing Quality (MS Quality) is a multiparameter sonde based in open hardware and software designed to monitor water quality parameters in a wide range of applications, including fish farms, rivers, lakes, or fishways. The device is easily configurable without needing external applications by standard USB connection. MS Quality features water quality sensors such as pH, dissolved oxygen, conductivity and water temperature. The sensor suite is configurable, thus it is possible to include other water quality, water level (ultrasound, pressure) or other environmental (air temperature, humidity, barometric pressure) sensors. MS Quality can work standalone as an autonomous independent sensing platform (gateway + sensing node) or inside a sensor network (node), thanks to the on-board communication modules. The programmable recording and transmission time provides an ideal solution for long time monitoring of environmental variables. The system is compatible with our on-line management platform.

The new MC Pressure Logger is based in the Sentinel board. It can be used to monitor water levels or absolute pressure changes in a wide range of applications, including rivers, lakes, dams, fishways, tidal areas, and groundwater. The logger is easily configurable by WiFi. This logger features a high precision pressure sensor in a stainless steel housing and factory-calibrated temperature sensor, both embedded in a durable IP68 polycarbonate housing. The programmable recording time provides an ideal solution for long time recording of water level, pressure and temperature in monitoring campaigns, research studies, etc.

Version 2.0

The MC Shadow operates on the Sentinel board. It is a submersible device positioned within the detection zone of an RFID antenna to ensure continuous operation. Additionally, it can record water temperature if submerged and is easily configurable via WiFi. The device covers and uncovers a PIT tag at adjustable timed intervals. Any discrepancies in the detection record would signify a malfunction of the reader, antenna, or power source.The circuit runs up to 5 year on a rechargeable Lithium cells.

Version 1.0

The MC Multi is a multipurpose datalogger and sensing node powered by the MC Sentinel board. This low-cost platform can accommodate multiple sensors all in one, including humidity, temperature, pressure, light, ultrasound, laser, infrared, and more, along with various communication alternatives such as radio or Wi-Fi. It can function as a standalone autonomous sensing platform or as part of a sensor network and can be easily configured wirelessly. Electronics are embedded in durable IP68 ABS housing. Its low power consumption makes it an ideal solution for environmental monitoring, and it is compatible with our online management and configuration platform.

Version 2.0

The MC Gateway, serving as the central hub of our sensor network solutions, is powered by a Raspberry Pi. It is not only compatible with our sensing solutions but also with commercially available ones, such as RFID PiT-Tag technology. Equipped with scheduled Python scripts, it can perform edge computing and submit online queries with collected data. Additionally, it features a 4G modem with a SIM card, providing remote access to users for on-site configuration. Its high configurability and straightforward design make it an ideal solution for developing custom sensor networks.

The Open Drifter (OD) is a small river drifter developed by the Centre for Biorobotics at Tallinn University of Technology and supported by GEA. The OD is an IoT device that can provide real-time estimates of position, travel speed, accelerations, orientations, or magnetic fields using mobile or radio communication at 1 Hz as well as onboard recording at 5-10 Hz. These properties make the drifter an ideal tool for the instantaneous characterization of small to large river streams. The OD is developed with low-cost open software and hardware which makes affordable the scalability of its production.

The Fish Tracker, consists of an optical-based fish counter, comprising (1) an infrared pulse emitter, (2) an infrared pulse receiver, (3) a processing unit and data transmission unit, which can be via GSM modem (4) or satellite modem (5). The control of the counter is carried out through a software solution that allows, in addition to counting the number of fish passing through the system, determining the speed and direction of movement (upward or downward), and generating a scan of the fish's silhouette (length and height). Furthermore, open technologies (software and hardware) have been used, and a modular design principle, which minimizes costs and simplifies both the potential customizations of each installation and future improvements to the device.

Version 1.0

Escalas is a multipurpose platform for the assisted design, 1D simulation, assessment and correction of stepped fishways. Escalas architecture allows the evaluation of different hydraulic scenarios in the river, the dimensioning of the fishway considering fish physical needs, the study of any type of stepped fishway, and to test solutions for possible malfunctioning or to evaluate retrofitting scenarios to improve their performance.
