3. Wheather station C2-SENE Milan 3 BOSCH BME280 humidity / temperature / pressure SPI / I 2 C LPC 1115 microcontroller data acquisition, conversion and segregation YL-83 rain detection DO / AO SEN-08942 wind speed / wind direction / pluviometer DO / AO GSM/GPRS Module River level RS-232

4. River level measurement C2-SENE Milan 4 sensor How to connect to the C2-SENSE? + radio transceiver + controller radio transceiver Connection seems to be simple. Appropriate sensor has to be developed.

5. River level sensor: state of the art C2-SENE Milan 5 In most cases: Water level determination based on hydrostatic and atmospheric pressure. Two devices: first in the river, second next to it (reference point). Comparison of the measurements in selected points.

6. River level sensor: state of the art C2-SENE Milan 6 Why are these inappropriate for the C2-SENSE? communication incompatibilities, not easy (quick) to set up, requires interference with the environment, definitely not low cost.

7. River level sensor: conception 1 C2-SENE Milan 7 Based on the GPS placed on the buoy. Main problem: uncertainty concerning GPS accuracy, has to be checked experimentaly

8. River level sensor: conception 2 C2-SENE Milan 8 Based on based on the difference in atmospheric pressure Current status: high accuracy pressure sensors was selected(MPXH6115A6U), two nodes in development state to experimental stage air pressure (reference level) air pressure on the buoy level (river level) radio communication
