Keep your aquarium fish healthy with a Raspberry Pi monitoring system that tracks pH, temperature, and water level in real-time. Get instant alerts on your phone when conditions go out of range, and automate feeding schedules. This project is perfect for aquarium hobbyists across India.
Why Monitor Your Fish Tank with Pi
Why Monitor Your Fish Tank with Pi is a fundamental concept for this project. Understanding the basics will help you configure your Raspberry Pi optimally for this use case.
Selecting pH and Temperature Sensors
- Raspberry Pi 4 or 5 (4GB+ recommended)
- MicroSD card (32GB+) or NVMe SSD for better performance
- Ethernet connection for reliable networking
- Appropriate case and cooling for 24/7 operation

Which pH sensor works with Raspberry Pi?
The DFRobot Gravity Analog pH Sensor Kit (₹3,000-4,000) is the most popular choice. It connects via an ADC (like ADS1115) since the Pi lacks analog inputs. Cheaper sensors exist but need frequent calibration.
Is the DS18B20 waterproof for aquarium use?
Yes, the DS18B20 waterproof probe variant is designed for submersion. It uses the 1-Wire protocol on GPIO4. Accuracy is ±0.5°C which is sufficient for aquarium monitoring.
Can this system automatically do water changes?
Partially. You can automate topping off evaporated water using a float switch and a pump. Full water changes still require manual intervention for draining and refilling.
How do I get alerts on my phone?
Use Telegram Bot API or Pushover for instant notifications. When pH drops below 6.5 or temperature exceeds 30°C, the Pi sends an alert. Python libraries make this easy to implement.
