Monitoring of water quality in tilapia farms with IoT technology

Abstract

Water quality monitoring for tilapia farming is essential to increase the productivity and competitiveness of fish farmers, requiring the introduction of technologies that help reduce vulnerability factors and support the processes of tilapia farming, fattening and harvesting. Based on this approach, an electronic prototype was designed and implemented to monitor water quality parameters, such as temperature, pH and dissolved oxygen, in order to identify the optimal values that would guarantee the reduction of mortality rates in tilapia cultures. The tests were conducted in a controlled environment. The prototype hardware consists of an electronic conditioning section and a microcontroller, in which the process of sampling, conditioning, data acquisition and processing is performed for sending and storage in the cloud. The information is sent by Wifi connection to our cloud storage provider, which allows our software to show the user the variations of the water parameter measurements in graphical form and the user can take corrective actions according to each situation. This prototype is expected to contribute to the improvement of productive activities in aquaculture, increasing the competitiveness of producers and reducing mortality rates in tilapia.
