Aquaponics

Aquaponics systems need to be carefully tended to keep them working well as both the fish and the hydroponic plants need a consistent environment. We’ve made a solution – a control and monitoring system – from a number of open-source elements and created software to integrate them together.

The system uses an Arduino Mega (massive ‘rispetto’ to them!) to connect to most of the sensors. We wrote code that collects sensor readings every second and sends them over Ethernet using the MQTT protocol. We chose MQTT because it’s a lightweight solution that’s a great fit for our needs, and there are high quality libraries available for Arduino and Raspberry Pi.
