Hydroponics pH Monitor Kit with Arduino Uno + Sensor
Hydroponics Water Quality Monitor Kit with Arduino Uno – pH, TDS & Turbidity
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your Arduino Uno into a full-featured water quality station that monitors pH, total dissolved solids (TDS/EC), and turbidity — all displayed on a clear 16×2 LCD. Whether you’re fine-tuning a hydroponic nutrient solution, checking water safety for drinking, or building a CBSE science investigatory project, this kit gives you a complete sensing platform ready to deploy on a single breadboard.
What You'll Build
You'll assemble a sensor suite that simultaneously reads pH, TDS/EC, and turbidity from a water sample, then displays live values on a bright LCD. The system uses pre-loaded logic to classify water safety — flagging samples as safe or unsafe for drinking based on turbidity thresholds and TDS limits. When connected to a hydroponic reservoir, it helps you keep nutrients perfectly balanced and avoid root rot or algae blooms.
What You'll Learn
- Calibrate analog pH sensors for accurate hydroponic nutrient monitoring
- Measure total dissolved solids (TDS/EC) to maintain ideal nutrient concentration
- Read turbidity values to assess water clarity and classify drinking water safety
- Integrate an I2C LCD module to display real-time water quality data

Who This Kit Is For
This kit is built for CBSE Class 11-12 students crafting investigatory projects on water quality, B.Tech ECE/EEE undergraduates exploring sensor fusion and agritech, and Smart India Hackathon teams prototyping hydroponic automation. It also plugs directly into ATL Tinkering Lab sessions and summer training programs at IIT, NIT, VIT, and BITS Pilani.
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 a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to chat with the AI companion, which knows every wire and code snippet for this project. You can also reach our support team on WhatsApp for human backup.
Can this kit actually test if drinking water is safe?
It measures turbidity and TDS, two critical indicators, and applies WHO-inspired thresholds to classify water as safe or unsafe. The kit is designed for learning and experimentation — not as a certified testing device — but the logic mirrors real water quality standards.
Do I need to solder anything?
No soldering is required. All connections use a breadboard and male-to-male jumper wires, so you can assemble, test, and modify the circuit in minutes.
What if a sensor is damaged out of the box?
Every component is covered by our 7-day manufacturing defect replacement policy. Contact us via WhatsApp or email and we’ll ship a replacement at no cost.
