Project description:
This is the first answer sheet of the project owner using EasyEDA as a rookie. Although there are many defects... but with the help of EasyEDA, these are all minor problems~ 
Application scenarios: smart home, environmental monitoring.
Function introduction: It can be directly connected to 220V, can detect ambient air quality, can detect ambient temperature and humidity, ambient light, and comes with a 4-digit LED digital tube display and a 0.96-inch OLED display.
Open source agreement: GPL-3.0
Design and selection:
This work has the advantages of practicality, personalization, and integration. The production process is simple and easy to understand, suitable for personal DIY.
CCS811 was originally used for air quality detection. After testing, it was found that there would be data abnormalities, and it was later replaced with SGP30. (Maybe it's a wiring or program problem?)
The BH1750 sensor is used for ambient light detection. The
temperature and humidity detection uses HTU21D + DS18B20.
The digital tube driver uses TM1637.
The Oled uses SSD1306
. In order to realize the remote switching of lights on and off on the mobile phone (computer, air conditioner, etc.), a relay with optocoupler isolation is added for driving.
Design process:
Hardware: Directly refer to the datasheet provided by the manufacturer. Remember to use DRC after drawing.
Software: Use ESPHOME in HomeAssistant as the platform and build it directly.
Physical display:
Running effect:
Program:
Note: In order to connect to the HomeAssistant platform, ESPHOME is directly used for programming. Of course, you can also use Espressif's official ESP-IDF for development, which will not be repeated here (/It is very stable during use and there are no outrageous bugs... So I'm lazy and won't write ESP-IDF.

Problem summary:
The digital tube only displays one time and minute separator? The same is true when programming with Arduino. I don't know why? I hope someone can help me solve
 
this problem. 2023/04/02: After looking at the schematic diagram, I found that the ports of these two points are not the same. The order of lighting is inconsistent. This may be the reason.
