Evaporative smart air humidifier based on ESP32

----------------------------------------Updated on 2021/01/26---- --------------------------------------------------

The board is already being prototyped. Regarding the PCB in the project, please note that it is currently in the functional verification stage. The shape of the board needs to be modified according to the shell size, so it is not the final version.

-------------------------------------Updated on 2021/01/15---- ----------------------------------------

I have drawn a version of the board, and I plan to make a version first to try out the function.

----------------------------------------First version released on 2020/01/13--- ----------------------------------------

At present, each humidifier has its own characteristics, but more or less all of them lack some of the functions I want to achieve, so I want to add some of the requirements and make one myself.

I have a little time recently, so I will draw the picture first, and will add it in subsequent updates.

Currently, we are considering using ESP32 as the main control to realize automatic query of network time and temperature, and to cooperate with local sensors to achieve intelligent humidification.

Local sensor:

1.SHT-20 temperature and humidity sensor

2. Ambient light sensor

3. Water tank water level sensor

4. Heater temperature control (implemented using NTC thermistor)

Cloud query is expected to implement the following functions:

1. Automatic date and time correction

2. Weather information query, if rain is expected in the future, the humidification amount will be intelligently reduced

The encoder is used locally to implement menu operations, and all settings can be performed with one knob; the network configuration is performed using html pages.

The screen is currently considering using a 240*320 LCD screen for status display.

I took the time to lay out the PCB and lay it out slowly~

APP control cannot be realized because I currently have no Android programming skills. You can ask your friends later.

If you have any questions, please point them out.
