+
+The MCP9808 Temperature sensor allows you to use your MCP9808
+(`datasheet <http://ww1.microchip.com/downloads/en/DeviceDoc/25095A.pdf>`__,
+`Adafruit <https://www.adafruit.com/product/1782>`__) sensors with
+ESPHome. The :ref:`I²C Bus <i2c>` is
+required to be set up in your configuration for this sensor to work.
