The ``max6675`` temperature sensor allows you to use your max6675 thermocouple
|
|
temperature sensor (`datasheet <https://datasheets.maximintegrated.com/en/ds/MAX6675.pdf>`__, `sainsmart`_) with ESPHome

|
|
As the communication with the MAX66775 is done using SPI, you need
|
|
to have an :ref:`spi bus <spi>` in your configuration with the **miso_pin** set (mosi is not required).
|
|
|
|
Connect ``GND`` to ``GND``, ``VCC`` to ``3.3V`` and the other three ``MISO`` (or ``SO`` for short),
|
|
``CS`` and ``CLOCK`` (or ``CLK``) to free GPIO pins.

Configuration variables:
|
|
------------------------
|
|
|
|
- **name** (**Required**, string): The name for the temperature sensor.
|
|
- **cs_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The Chip Select pin of the SPI interface.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
|
|
|
|
- **spi_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`SPI Component <spi>` if you want
|
|
to use multiple SPI buses.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
