Tips

To get started, connect the CO2 sensor to the Calliope mini using the included JST cable and I2C pins. Use MakeCode or MicroPython to read CO2 values and display them on the LED matrix. For accurate measurements, allow the sensor to stabilize for a few minutes after powering. The kit is ideal for projects like classroom air quality monitors, ventilation alerts, or data logging experiments.
