AI Fish Tank Based on ESP32

Function List:

2-channel relay,
2-channel aquarium LED lighting (supports stepless dimming),
1-channel RGB lighting (supports stepless dimming),
3-ADC: water temperature, water level, pH value.
App Wi-Fi connection control.
App supports Android & iOS (WebView).

Hardware Design:
1. The schematic adopts a modular design, consisting of three

ESP32 core boards with
IO driver and
power supply functions

. 2. A 4-layer board design is used:

top layer
signal layer
, 5V internal power layer,
bottom layer.

 
3. Routing & 3D vision

priority: pin signal control routing, minimizing the number of layers.
The 5V layer provides high current routing, but a large trace will be provided on the top layer to further facilitate high current routing.
All interfaces are located at the edge.
Flexible access to ESP32 development boards for easy reuse.
2D/3D images are not allowed (related to pornography?).

4. Board fabrication and soldering.
 
5. Power-on debugging.
6. Programming:
The intention is to write a program based on Arduino to control the content, but this is still in the learning stage, and the functionality is not yet fully implemented. The project source code will be released after further completion.
The program functions are as follows:
Hardware driver module
1. 2-channel relay 2. 3-channel electrodeless lamp 3. Light sensor 4. Temperature sensor 5. Encoder driver 6. OLED 7. Digital tube 8. Current, voltage
