Fish farming ponds with IoT sensors

The Challenge

The client operated 14 ponds with oxygenation pumps that relied on manual hourly checks. A 30-minute failure in a pump meant biomass loss: oxygen drops rapidly and the fish do not survive. Furthermore, energy costs were blind — pumps operated at a constant power regardless of the time of day or actual demand.

Our Solution

We designed an end-to-end monitoring system:

  • Proprietary hardware: ESP32 sensors with dissolved oxygen, temperature, and electrical current modules for each pump.
  • LoRa connectivity: sensors send data to the central gateway without relying on Wi-Fi, covering 2 km between ponds.
  • Web dashboard: real-time visualization with automatic alerts via SMS if a pump drops below the threshold.
  • Smart modulation: the system regulates the power of each pump according to dissolved oxygen levels, instead of operating at 100% at all times.

Measurable Results

38%

Energy savings

Through pump modulation based on actual demand, rather than constant operation.

Losses due to undetected failures

Automatic SMS alerts in less than 30 seconds upon detecting anomalies.

Operational visibility

Access to the dashboard from any device, without being physically at the plant.

"We went from checking pumps with a flashlight at 3 AM to receiving an alert on our mobile phone if anything moves. The plant runs itself."
