The ``dallas_temp`` component allows you to use
|
|
|
|
|
`DS18B20 <https://www.adafruit.com/product/374>`__
|
|
|
|
|
(`datasheet <https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf>`__)
|
|
|
|
|
and similar 1-Wire temperature sensors. A :ref:`1-Wire bus <one_wire>` is
|
|
|
|
|
required to be set up in your configuration for this sensor to work.
