Arduino Sensor

The arduino sensor platform allows you to get an numerical values from an analog input pin of an Arduino board. Usually the value is between 0 and 1024.

To enable an Arduino sensor with Home Assistant, add the following section to your configuration.yaml file:

# Example configuration.yaml entry
  platform: arduino
      name: Door switch
      type: analog
      name: Brightness
      type: analog

Configuration variables:

  • pins (Required): Array of pins to use. The number corresponds with the pin numbering schema of your board.
    • name: Name that will be used in the frontend for the pin.
    • type: The type of the pin. At the moment only ‘analog’ is supported.

The 6 analog pins of an Arduino UNO are numbered from A0 to A5.
