From chemical production to hydroponics, conductivity is a fundamental measurement of water chemistry. The EZO-EC Circuit reads conductivity, salinity, and TDS (PPM). It gives you same accuracy found in costly bench-top conductivity meters.

Connect your EC sensor to this circuit to create a workable signal for your microprocessor using UART or I2C protocol.
Works with any brand and type of EC sensor.

It may happen that you want to return an order. Because the product does not suit you, maybe there is another reason why you would not want the order. Whatever the reason, you have the right to cancel your order up to 14 days after receipt without giving a reason.

After cancellation you have 14 days to return your product. You will then be credited 85% order amount excluding shipping. For more information click the following link: /pages/shipping-and-returns
