Project introduction:

   The fish tank system will continue to update functions. At present, the data communication between wizfi360 and server has been realized. The electrical appliances (water pump, oxygen pump, fill light, heating rod) on the fish tank can be controlled by the rotary encoder at the end of the fish tank to obtain the temperature of the fish tank. You can also remotely control the electrical appliances on the fish tank through the TCP server, and the status and temperature of the fish tank can be displayed on the TFT display. The functions to be added in the next step are that the TFT display and rotary encoder on the fish tank end will be modified to configure Wifi information, the server will be ported to the web end, data and control status will be transmitted through MQtt, and Android App will be added to remotely control the fish tank and obtain the fish tank information.
