IMPLEMENTATION OF MICROCONTROLLER BASED EARTH POND WATER QUALITY MONITORING SYSTEM USING SOLAR POWER AND BLUETOOTH TECHNOLOGY IN NIGERIA FISH FARMING SYSTEM
ABSTRACT
This research is motivated towards implementing a solar-powered water quality monitoring and control system for a warm water earth pond in real-time. Deploying an efficient monitoring and control system to fish farms will enhance the increase of yield, saves time, cost, and increase productivity in Nigeria. The system is designed to measure, analyse, and control the various relevant parameters: temperature, pH, and turbidity. To achieve this, sensors are used to detect changes in the environmental conditions of the pond as regards aforementioned parameters to determine the state of the pond. Furthermore, the system uses actuators as a mechanism to control the inflow and outflow of water using the control signal received from the processing unit. A successful inquiry was established between the Bluetooth module and the hands-free Bluetooth handset. This made it possible to monitor the real-time status of the warm water earth pond through the Bluetooth wireless communication. Noise and instability were observed in the data collected on the Arduino Integrated Development Environment (IDE), and this was resolved using a running average filter algorithm. The research shows that the linearity of the pH sensor is good, haven obtained an R2 value of 0.9988.
