Pimoroni PIM587 SCD41 CO2 Sensor Breakout 400-5000 ppm

SKU CH-9KW9-JRNGW

Measures CO₂ from 400 to 5000 ppm plus temperature and humidity over I2C with a Qwiic/STEMMA QT connector

  • Measures CO₂ from 400 to 5000 ppm with photoacoustic precision
  • Also reads temperature and relative humidity in one module
  • Connects via I²C at address 0x62 with Qwiic/STEMMA QT plug
  • Works at 3–5 V with reverse-polarity protection on Breakout Garden header
  • Raspberry Pi and Pico libraries available for Python, C++ and MicroPython

Pimoroni SCD41 CO2 Sensor Breakout

The Pimoroni PIM587 breakout board carries a Sensirion SCD41 sensor that measures carbon dioxide from 400 to 5000 ppm using photoacoustic technology. It also reports temperature and relative humidity. The board communicates over I2C at address 0x62 and includes a Qwiic/STEMMA QT connector for solderless wiring.

Makers adding air-quality data to Raspberry Pi

Python libraries support Raspberry Pi and C++ or MicroPython libraries support Raspberry Pi Pico, so the board suits developers prototyping indoor-environment monitors. Builders who need CO2 readings beyond 5000 ppm or who require a different communication protocol should look at other sensor modules.

I2C address 0x62 and 400-5000 ppm range

The fixed I2C address 0x62 means only one SCD41 can share a bus without an address multiplexer. The measurement range tops out at 5000 ppm, which covers typical indoor spaces but not high-concentration environments such as greenhouses or industrial processes.

Questions about this item

How can I confirm the SCD41 breakout is reading CO₂ correctly after wiring it up?

Apply power, run the Python library on a Raspberry Pi or the MicroPython library on a Pico, and verify the serial output shows CO₂ values between 400 and 5000 ppm alongside temperature and humidity readings.

What ships with the PIM587 breakout and what must I source separately?

The board includes the Sensirion SCD41 sensor, a Qwiic/STEMMA QT connector and Raspberry Pi-compatible pinout; you must supply a Raspberry Pi, Pico or other 3-5 V I²C host and any jumper wires or HAT header you prefer.

Which CO₂ measurement range version should I choose for indoor air-quality monitoring?

The PIM587 uses the SCD41 calibrated from 400 to 5000 ppm, which covers typical indoor environments; no alternative range versions are offered for this model.
