Design of intelligent fish tank system based on single chip microcomputer
Abstract: With the continuous improvement of people’s living standards, exquisite life has become a fashion. In order to add interest to life, decorate the home environment, breeding ornamental fish has become a trend, in order to create a good living environment for fish, the design of intelligent fish environmental monitoring system is essential.
This paper uses STM32 as the main control chip and sensor to develop a new fish monitoring system. TDS water quality module is used to detect the turbidity of the water in the aquarium, waterproof DS18B20 is used to detect the water temperature in the aquarium, ultrasonic module is used to detect the water level of the aquarium, PH sensor is used to detect the PH value of the water, photoresistor is used to detect the light value, OLED display is used to display the relevant monitoring value, and the threshold can be set by buttons. The relay can also be controlled to perform related work to achieve the purpose of adjusting the aquarium water environment. In addition, the WiFi module is also used to achieve remote control of the aquarium.
The actual test shows that the system can solve the problems of short communication distance and high power consumption faced by intelligent fish tanks. The test shows that the system parameters can be controlled stably, and the error is small, and the survival rate of fish can be improved effectively.
