Intelligent aquarium water filtration and oxygenation system

 
Overview
1. The main controller is based on an STM32G030F6 for ambient temperature detection and PWM power adjustment of the water pump (with timer or day/night mode to reduce noise).
2. A CH224X chip is used to induce voltage from the PD power supply to power the microcontroller and water pump.
3. A 0.6-inch OLED screen allows for intuitive viewing of power supply voltage parameters and PWM output duty cycle parameters.
4. Two NTC temperature sensors detect and display the ambient temperature in real time for easy viewing. It can also be placed in a fish tank to monitor water temperature and control heating or cooling equipment.
