Hi everyone,

I’m building a simple air quality monitor using R1BBIT and wanted to share the approach and get feedback on best practices.


📌 Goal

Read data from an SCD41 sensor (CO2, temperature, humidity) and display it on a 320x240 SPI screen in real time.


⚙️ Current Approach

  • I2C for SCD41
  • SPI display for output
  • Periodic sensor reading (~5 seconds interval)
  • Updating only changed values on screen (to avoid flickering)
