The ``mcp9600`` sensor platform allows you to use your MCP9600 and MCP9601
|
||
|
|
(`datasheet <https://cdn-learn.adafruit.com/assets/assets/000/105/040/original/MCP960X-Data-Sheet-20005426%281%29.pdf>`__,

`Adafruit`_) to measure the temperature of a connected thermocouple while also measuring the ambient temperature around the sensor with ESPHome. :ref:`I²C <i2c>` is
|
||
|
|
required to be set up in your configuration for this sensor to work.
|
||
|
|
|
||
|
|
.. warning::
|
||
|
|
|
||
|
|
The :ref:`I²C <i2c>` bus must be set to a minimum of ``100khz`` due to the limitations of the MCP9600 and MCP9601.
