Build a Smart Hydroponics Nutrient Monitor with Arduino & OLED — Hydroponics EC Meter Variant 12 Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Ever wondered how hydroponic farmers keep their nutrient solution perfectly balanced? With this kit, you’ll build a compact device that measures electrical conductivity (EC) and displays the total dissolved solids (TDS) in parts per million on a bright OLED screen. A red LED lights up when the concentration drifts out of the ideal range, so your plants get exactly what they need — a first step into precision agriculture.

What You'll Build

A real-time nutrient monitoring tool that reads the strength of your hydroponic solution, shows the PPM on a crisp 0.96‑inch OLED, and gives an instant visual alert with an LED when it’s time to adjust. It’s a fully functional prototype you can mount next to your home‑grown leafy greens or strawberries.

What You'll Learn

• Sensing electrical conductivity with a TDS probe and converting raw analog readings into PPM values
• Driving an I2C OLED display to show live sensor data with Arduino libraries
• Coding conditional statements that compare readings to user‑defined thresholds and switch LEDs on/off
• Calibrating the sensor using a known conductivity standard and compensating for temperature effects
