A low-cost, accessible, and high-performing Arduino-based seawater pH control system for biological applications.

ABSTRACT: In the last two decades, the need for seawater pH control methodologies paralleled the rise in attention to the biological impacts of ocean acidification. Many effective and high-performing systems have been created, but they are often expensive, complex, and difficult to establish. We developed a system that is similarly high performing, but at a low cost and with a simple and accessible design. This system is controlled by an Arduino Nano, an open-source electronics platform, which regulates the flow of CO₂ gas through electric solenoid valves. The Arduino and other inexpensive materials total ∼$150 (plus CO₂ gas and regulator), and a new treatment can be added for less than $35. Easy-to-learn code and simple wire-to-connect hardware make the design extremely access
