# Display
If you're using a device with OLED display, or if you add such one to the I2C bus, the device shows live data on the display. You can flip between pages showing pax, time, GPS and BME sensor data by pressing the button of the device.
If you're using a device with OLED display, or if you add such one to the I2C bus, the device shows live data on the display. You can flip display pages showing
- recent count of pax
- histogram
- GPS data
- BME sensor data
- Time of day
by pressing the button of the device.
