ESP8266 with OLED, DHT11, GY-30 and BMP180

My fourth trying with Arduino and show lux data on a mini OLED display.
Its display my text who made this code and after that its will shows the data.

Parts:

• Adafruit ESP8266 as NodeMCU 1.0 (ESP-12E modul),
• 0.96″ 128x64 mini OLED display (I use white color for that project),
• DHT11 temperature and humidity sensor
• GY-30 Light Intensity Sensor
• BMP180 Air Pressure Sensor
• Jumper cables.

You can see a picture from the full setup here:

Arduino Modules:

• Adafruit_SSD1306,
• Adafruit_GFX,
• DHT
• BH1750 for the GY-30
• SFE_BMP180 for the BMP180 Air Pressure Sensor

It is the next step on my previous project as

Connection:

• Display GND to ESP G (Ground beside the 3V)
• Display VCC to ESP 3V
• Display SCL to ESP D1 as GPIO 1
• Display SDA to ESP D2 as GPIO 2
• DHT + to ESP 3V (Can be the same as where the display VCC)
• DHT - to ESP G (Can be the same as where the display GND)
• DHT OUT to ESO D5 as GPIO 14
• GY-30 VCC to ESP 3V (Can be the same as where the display VCC)
• GY-30 GND to ESP G (Can be the same as where the display GND)
• GY-30 SCL to ESP D1 as GPIO 1 (Can be the same as where the display SCL)
• GY-30 SDA to ESP D2 as GPIO 2 (Can be the same as where the display SDA)
• BMP180 VIN to ESP 3V (Can be the same as where the display VCC)
• BMP180 GND to ESP G (Can be the same as where the display GND)
• BMP180 SCL to ESP D1 as GPIO 1 (Can be the same as where the display SCL)
• BMP180 SDA to ESP D2 as GPIO 2 (Can be the same as where the display SDA)

Coding in Arduino IDE 1.8.19
I made this code from sources of the internet. There is no copyright, use it as you want.

If you want to use with Thingspeak, You can find it as another branch in this repository.
