+    :description: Instructions for setting up HDC302x temperature and humidity sensor for use with ESPHome.

+    :keywords: HDC3020, HDC3021, HDC3022
+
+The `hdc302x` sensor platform allows you to use your HDC302x temperature and humidity sensor
+(`datasheet <https://www.ti.com/lit/ds/symlink/hdc3020.pdf>`__,
+`Adafruit <https://www.adafruit.com/product/5989>`__) with ESPHome.
+
+The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.

+    sensor:
+      - platform: hdc302x
+        temperature:
+          name: "Temperature"
+        humidity:
+          name: "Relative Humidity"
+        update_interval: 60s
+
+Configuration variables:
+------------------------
+
+- **temperature** (*Optional*): Temperature.
+
+  - All options from :ref:`Sensor <config-sensor>`.
+
+- **humidity** (*Optional*): Relative Humidity.
+
+  - All options from :ref:`Sensor <config-sensor>`.
+
+- **power_mode** (*Optional*, enum): The Power Mode used when triggering temperature and humidity readings. This
+  affects the accuracy of readings and the power usage of the sensor.
+
+  - ``HIGH_ACCURACY`` (Default): Low Power Mode 0 - Highest accuracy, slower, higher power usage.
+  - ``BALANCED``
+  - ``LOW_POWER``
+  - ``ULTRA_LOW_POWER``: Low Power Mode 3 - Lowest power usage, faster, less accuracy.
+
+- **heater** (*Optional*, boolean): If true, enable the relative humidity sensor's integrated heater.
+  *Note: This will significantly impact temperature readings.*
+
+- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
+
+Heater Configuration:
+---------------------
+
+The HDC302X includes an integrated heater in the relative humidity sensor, which is intended to remove condensation
+from the sensor in high humidity environments. This can help maintain accurate humidity measurements.
+
+The heater can be enabled by setting ``heater`` to ``true``. This will run the heater with the default sensor settings.
+
+See the (`datasheet <https://www.ti.com/lit/ds/symlink/hdc3020.pdf>`__) for more information about heater operation.
