The configuration “LEGINO” is based on the “Outdoor” model and is designed to meet the project requirements. The name comes from the site of the first intallation of this configuration (Legino, ACROLAB at the University Campus of Savona, SV).

The measuring chain involves the combination of a level sensor hydrometric ultrasound and a remote station made in accordance with the Paradigm.

The station is the ACROSTATION device family "O" (outdoor) released in 03a release.

In the station it is included Electronic card ACROboard "Station" v02, in its latest release. This card is dedicated both to the collection function and data transmission (via GPRS, with internal antenna) that the supply management of energy to the components (and charging the buffer battery).

Power is supplied by a 20W Solar Panel, combined with a 12V buffer battery and 12 Ah. The connection between the station and the solar panel is through the dedicated cable and protected by the sheath against solar radiation and atmospheric agents.

As regards the actual operation of the configuration, the station receives the signal from the instrument and generates, with the same continuity, the time series data in native form. The configuration of the firmware (pre-installed in the microcontroller onboard the ACROBoard Station, for the first ignition is stored in the memory of the basic configuration files) allows metadating, the time integration, and a first control accuracy by filtering any values consistent.

Finally, the GPRS module, with a non-encrypted HTTP protocol, transmits data in accordance with the configuration file ACRONETWORK infrastructure, with update rates of the order of minutes

Under normal irradiation of the site, the power is ensured exclusively from solar sources via the supplied panel to the station.

The configuration allows the addition, even in retrospect, the Optional Modules Back-up described below:

- Energy: High Capacity Battery, able to support the measurement system from the energy point of view for long periods;

- Communication: Radio Satellite low frequency, can not be influenced by the weather conditions.


Download Box

This area includes both the firmware dedicated to this specific Configuration and the basic implementation. You can use the firmware to manage the electronic side of the apparatuses, while the basic implementation is fundamental to run the system (define parameters, position, etc.). You can easily download them or find them in the GitHub repository.


The Firmware is the program (sequence of instructions) that has to be integrated directly into the microcontroller placed on the ACROBoard selected for the Configuration. Its main purpose is to start the MIC as well as to interact with the other electronic items. Here you can find the .7z, the .zip folders and the link to the GitHub repository.


Basic Implementation

This set of files is coupled with the firmware and is fundamental to set specific operational parameters (position, frequency of logging, etc.).Here you can find the .7z, the .zip folders and the link to the GitHub repository.
