Abstract
Ornamental fish have become a popular pet choice due to their convenience and attractiveness. In order to protect the growth and health of ornamental fish and timely improve the water quality conditions, a solar powered wireless water quality monitoring system for ornamental fish was proposed and developed. The system includes the solar power supply module, sensing module and master control module. The solar power supply module includes the solar panel with solar power management module. The sensing module includes the pH and temperature sensor and the master control unit module includes the microprocessor, data remote transmission unit and the organic light-emitting diode (OLED) screen display. The system sustainability performance, sensing performance, and the system evaluation of the solar powered wireless monitoring system for water quality were analyzed and evaluated. The system could effectively acquire the pH and temperature sensor data in water by solar energy powering and wirelessly transmit to the remote monitoring devices such as the smart phone by WiFi or Bluetooth. The proposed system has a potential application example for many kinds of water quality monitoring by renewable energy harvesting to improve the sustainability and quality.
