Czujnik BME280:
| I2C Wiring | ESP NodeMCU Pinout |
|---|---|
| SCL | D1 |
| SDA | D2 |
| VIN | 3V |
| GND | G |
SPS30:
| I2C Wiring | ESP NodeMCU Pinout |
|---|---|
| 5V | VIN |
| SCL | D1 |
| SDA | D2 |
| GND | G |
| SEL | G |
Uwaga:
Połączenie magistrali I2C z czujnika SPS30 i czujnika BME280, czyli SDA i SCL przychodzi do tego samego pinu na ESP8266 kolejno D1 i D2
