+SFA30 Formaldehyde Sensor
+=========================
+
+.. seo::
+    :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.

+    # Example configuration entry
+    sensor:
+      - platform: sfa30
+        formaldehyde:
+          name: "Formaldehyde"
+        temperature:
+          name: "Temperature"
+        humidity:
+          name: "Humidity"
+
+
+Configuration variables:
+------------------------
+
+- **formaldehyde** (*Optional*): The information for the Formaldehyde sensor.
+  All options from :ref:`Sensor <config-sensor>`.
+
+- **temperature** (*Optional*): The information for the Temperature sensor.
+  All options from :ref:`Sensor <config-sensor>`.
+
+
+- **humidity** (*Optional*): The information for the Humidity sensor.
+  All options from :ref:`Sensor <config-sensor>`.
+
+
+- **address** (*Optional*, int): Manually specify the I²C address of the sensor.
+  Defaults to ``0x5D``.
+
+- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
+  sensor. Defaults to ``60s``.
