Deltares
Salinity Sensor
Custom hardware and app
How do we make water quality measurement devices accessible to the majority and ensure developing countries have more ways to access and confirm the quality of their water?
The Challenge
Checking water quality in developing countries
Find a low cost alternative to $50,000 analysis machines that can provide the same reliability for basic reading to measure quality of water.
The Idea
A cheap sensor that connects to a mobile phone
By moving the brains of the analysis machines into smartphones, we can bring the power of these machines within the grasp of farmers around the world for a mere $2.
With basic circuitry, an audio jack and machine learning, farmers can use any cheap smartphone to quickly check whether their water is safe to use for irrigation.
The Solution
Create a dongle with a basic measurement device that attaches to a smartphone via the audio jack.
By sending a signal over the speaker wires and receiving the measurement over the microphone wire, a low-cost smartphone can calculate the salinity using an app.
