The Sensirion SHT31 is an I²C device in the LabWired part catalog. Its catalog type is sht31. It connects to the MCU over I²C at the default address 0x44. The catalog gives a supply range of 2.15–5.5 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.
From the catalog: Declarative I²C kit — model is core/configs/devices/sht31.yaml (GenericI2cDevice), no per-part Rust.

Simulated device model
Built from the datasheet. Implemented from the part’s register documentation and exercised by automated tests. Nothing physical was ever placed next to it.
| Pin | Electrical type | Function |

VCC | Power input | Supply |
GND | Power input | Supply |
SDA | Open-drain | I²C data (SDA) |
SCL | Open-drain | I²C clock (SCL) |
These catalog parts use the same default address. Two parts at one address cannot share one bus segment. A bus switch such as the TCA9548A puts them on separate segments.
