MICS-4514 being sold on AliExpress has the same model number, but is a different board that doesn't use I²C Bus. Adding a note about this as a warning for anyone shopping for this sensor.

|
This component exposes the different gas concentration sensors from the `MiCS-4514 <https://www.dfrobot.com/product-2417.html>`__. This is a differnet sensor than the MICS-4514 being sold on AliExpress.
|
|
|
|
.. note::
|
|
|
|
|
|
The sensor has a 3-minute warmup period where data is unreliable and ESPHome will only start publishing sensor values after this time.
|
|
If the sensor was already powered only, such as if you restarted or updated your ESPHome device, then it will start publishing immediately.
|
|
|
|
The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.
