Sensirion SCD41 CO₂

The Sensirion SCD41 CO₂ is an I²C device in the LabWired part catalog. Its catalog type is scd41. It connects to the MCU over I²C at the default address 0x62. The catalog gives a supply range of 2.4–5.5 V. It has 4 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How to simulate the Sensirion SCD41 CO₂ in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the Sensirion SCD41 CO₂ (catalog type scd41).
  3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 2.4–5.5 V.
  4. Connect SDA and SCL to the I²C data and clock pins of the board.
  5. Run the firmware. It finds the part on the I²C bus at 0x62 and reads and writes it as on hardware.
