MAX6675 K-Type Thermocouple Temperature Sensor ============================================== .. seo:: :description: Instructions for setting up MAX6675 Thermocouple temperature sensors. :image: max6675.jpg The ``max6675`` temperature sensor allows you to use your MAX6675 thermocouple temperature sensor (`datasheet `__, `SainSmart`_) with ESPHome .. figure:: images/max6675-full.jpg :align: center :width: 60.0% MAX6675 K-Type Thermocouple Temperature Sensor. .. _SainSmart: https://www.sainsmart.com/products/max6675-module-k-type-thermocouple-thermocouple-sensor-temperature-0-1024-for-arduino As the communication with the MAX66775 is done using SPI, you need to have an :ref:`SPI bus ` 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. .. figure:: images/temperature.png :align: center :width: 80.0% .. code-block:: yaml # Example configuration entry spi: miso_pin: D0 clk_pin: D1 sensor: - platform: max6675 name: "Living Room Temperature" cs_pin: D2 update_interval: 60s Configuration variables: ------------------------ - **name** (**Required**, string): The name for the temperature sensor. - **cs_pin** (**Required**, :ref:`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 ` 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 `.
