Full Octopus Unit: work in progress...
Individual Sensors:
What does it measure: It measures dissolved solids
How does it measure it?: The sensor uses electrical conductivity to determine solid concentration (Hancock).
Why is it important?: High TDS may indicate harmful contaminants.
What does it measure?:Measures water clarity
How does it work?: The sensor detects light scattering caused by suspended solids (Atlas Scientific).
Why is it important?: High turbidity signals poor water quality
What does it measure?: It measures water flow
How does it work?: A Turbine wheel with Hall Effect sensor calculates flow via pulse rate (Wikiseeed).
Why is it important?: It is critical for monitoring runoff and pollutant transport.
What does it measure?: It measures water temperature
How does it work?: A Thermistor measures resistance changes with heat ("Temperature and Water").
Why is it important?: Influences biological activity and chemical reactions.
What does it measure?: It measures the potential for certain chemical reactions.
How does it work? The probe measures the voltage difference between the solution and a reference solution (Atlas Scientific).
Why is it important: It shows how well water can cleanse itself.
What does it measure?: It measures water content in soil
How does it work?: The capacitive sensor measures charging rate affected by surrounding moisture
Why is it important?: Essential for water and heat energy transfer in ecosystems. It measures the water in the soil which in turn, influences the quality of the water. If it is low a drought may be coming.
What does it measure?: It measures hydrogen ion potential
How does it work?: It measures the voltage difference between the test solution and a reference electrode
Why is it important?: pH affects water chemistry and aquatic life.
What does it measure?: It measures water surface height
How does it work?: The conductive plates measure changes in conductivity caused by water contact.
Why is it important? Low levels indicate droughts or poor water management.
