Hydroponics EC Meter Kit with Arduino Uno + LED
Build a Hydroponics Nutrient Monitor with Arduino Uno & LED Alert
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine monitoring the exact nutrient strength of your hydroponic solution in real time. With this kit, you build a handheld EC/TDS meter that displays PPM on an OLED screen and lights up a red LED when levels fall outside the ideal range for plant growth.
What You'll Build
A compact, battery-powered conductivity meter with a clear OLED readout. It uses a TDS probe to measure electrical conductivity, converts to parts per million, and provides instant visual feedback via green (in-range) and red (out-of-range) LEDs. Perfect for checking your hydroponics nutrient solution right at the reservoir.
What You'll Learn
- Calibrate a TDS/EC sensor for accurate nutrient measurement
- Display real-time sensor data on an OLED screen using I2C communication
- Program conditional LED alerts based on PPM thresholds
- Use resistors and breadboard to build a stable circuit

Who This Kit Is For
This beginner-friendly kit is ideal for school students exploring smart farming (CBSE Class 11-12 agriculture projects), ATL Tinkering Lab innovators, or B.Tech freshers in ECE/EEE building their first IoT sensor system. Also great for hobbyists and kids aged 10+ who want to understand plant nutrition through electronics.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If
TDS conductivity sensor shows nutrient concentration in PPM on OLED. LED turns red when out of range.
