EZO™ Conductivity Circuit
| Article number: | Part # EZO-EC |
| Availability: | In stock (14) |
Connect your pH sensor to this circuit to create a workable signal for your microprocessor using UART or I2C protocol.
Works with any brand and type of pH sensor.
An E.C. (electrical conductivity) probe measures the electrical conductivity in a solution. It is commonly used in hydroponics, aquaculture and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.
Inside the conductivity probe, two electrodes are positioned opposite from each other, an AC voltage is applied to the electrodes causing cations to move to the negatively charged electrode, while the anions move to the positively electrode. The more free electrolyte the liquid contains, the higher the electrical conductivity
