:description: Instructions for setting up SFA30 Formaldehyde Sensor
:image: sfa30.jpg
The ``sfa30`` sensor platform allows you to use your Sensirion SFA30 Formaldehyde
(`datasheet <https://sensirion.com/media/documents/DEB1C6D6/63D92360/Sensirion_formaldehyde_sensors_datasheet_SFA30.pdf>`__) sensors with ESPHome.
The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.
This sensor supports both UART and I²C communication. However, at the moment only I²C communication is implemented.
