Abstract

This design revolves around the water environment detection of home intelligent fish tanks, aiming to create a more comfortable living environment for fish. The design takes the STC89C52 single-chip microcomputer with high integration, strong function, and fast response as the core, adopts the DS18B20 temperature sensor to detect water temperature, and monitors the water quality level in real time through the TS-300B turbidity sensor. After the sensors are connected to the devices, the analog-to-digital conversion is completed via the A/D conversion module to facilitate data processing by the single-chip microcomputer. It uses a timer to control the ULN2003 to drive the stepper motor rotation to realize the timed feeding function, and simultaneously controls the start and stop of the water circulation system and the oxygen pump. The system compares the preset temperature and turbidity parameter critical values with the real-time data displayed on the OLED screen, thereby starting water changing or other adjustment functions to correct the parameters, and completes the comprehensive control of the home intelligent fish tank water environment in cooperation with the buzzer alarm module.
