The communication module is responsible for sending real-time data to our server via radio or WiFi.
The energy supply module consists of a solar panel, a battery, and a solar charge regulator.
The control board module is the brain of the station. It is responsible for asking the sensors to take readings and for saving the data to a memory card. 
To take discrete samples from soils and the groundwater, sampling wells are installed at three different depths
Soil and groundwater dissolved O2 and CO2 
To monitor the groundwater depth, a water level sensor (i.e., piezometer) is placed inside a well containing a pipe with an open bottom.
In-stream electrical conductivity, turbidity and water level are measured using commercial solutions.
The water table oscillates according to the snowmelt and precipitation rate.
