This is my IPASS project for the last project of the first year HBO-ICT TI on the HU.
I use the SI7021 to measure the temperature and humidity of the room, and display the result on a Oled screen.
If you want to read the documentation, please go to The github page, or run the doxygen yourself.
The pins of my chips are connected as follows:
| CJMCU-8128 | Arduino | SSD1306 | ||
|---|---|---|---|---|
| VCC | <-> | 3V3 | <-> | VDD |
| GND | <-> | GND | <-> | GND |
| SDA | <-> | SDA Pin 21 | <-> | SDA |
| SCL | <-> | SCL Pin 22 | <-> | SCK |
| WAK | <-> | GND |
At the end of the project my code for the BMP280 and CCS811 sensors DOES NOT WORK! Hopefully I can find the time to fix them too, but no guarantees.
