Aquaculture Dissolved Oxygen Alert Kit with Arduino Uno + Sensor
Aquaculture Dissolved Oxygen Alert Kit with Arduino Uno + DO Sensor — Real-Time Monitoring & Automatic Aeration to Protect Fish Stocks
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Fish farmers lose entire stocks overnight because dissolved oxygen levels crash without warning. This kit empowers you to build a proactive electronic guard that continuously reads oxygen concentration and responds the moment it drops. Live DO data appears on an OLED screen, an alarm buzzes, and a relay instantly activates aeration equipment. The system you’ll create is ready for hatcheries, ornamental fish tanks, and small-scale aquaculture ponds.
What You'll Build
You’ll assemble a self-contained dissolved oxygen monitoring station. The OLED displays real-time DO values in mg/L, while the active buzzer provides a loud alert when oxygen falls below a safe threshold. The 5V relay module can directly switch an aerator pump or blower, letting you automate the response. Once calibrated, the entire setup runs on a 9V battery, making it portable and easy to deploy near any tank.
What You'll Learn
- Interface a galvanic dissolved oxygen sensor with Arduino Uno and interpret its analog output
- Calibrate a DO probe using air and zero‑oxygen solution for accurate readings
- Program a relay module to turn on/off aeration equipment based on sensor thresholds
- Drive an I2C OLED display to show live oxygen levels and status

Who This Kit Is For
This kit is perfect for CBSE Class 11–12 students exploring smart agriculture in their physics or computer science curriculum. B.Tech ECE/EEE learners will gain hands-on experience with sensor interfacing and automation—ideal for Smart India Hackathon projects. ATL Tinkering Labs and hobbyists from IIT/NIT/VIT/BITS will also find it a practical way to apply technology directly to India’s aquaculture challenges.
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 access the AI build companion, which walks you through each step. You can also reach out via WhatsApp for human assistance.
Does the dissolved oxygen sensor come pre-calibrated?
The sensor requires a simple two-point calibration in air and zero-oxygen solution, which the guide explains clearly.
Can I connect the relay directly to a heavy-duty aerator pump?
The 5V relay module can switch a separate circuit up to 10A 250V AC, but you must use proper wiring and a fuse for safety. The AI companion includes wiring diagrams.
What coding experience do I need?
You'll upload a provided Arduino sketch, so basic familiarity with the Arduino IDE is enough. The code is clearly commented for learning.
Galvanic DO probe signals low dissolved oxygen level in fish tank and triggers aeration relay automatically.
