:description: Instructions for setting up T6613 and T6615 sensors for ESPHome
:image: t6615.png
:keywords: t6613 t6615
The ``t6615`` sensor platform allows you to use T6613 and T6615 family sensors
(`amphenol`_) with ESPHome. T6613 sensors are unreferenced and require ABC to
calibrate daily, while the T6615 sensors have a sealed reference gas and
do not require ABC calibration. All ppm ranges are supported by this platform.

As the communication is done using UART, you need to have an :ref:`UART bus <uart>` in your configuration with the
``rx_pin`` connected to the TX pin of the device (pin 10) and the ``tx_pin`` connected to the RX Pin of the device (pin
11). The baud rate should be set to 19200.
Additionally, the T6613/15 sensors require 5V power, while most ESP platforms only output 3.3V from their onboard
regulator, so you may need some additional components to power up the sensor.

Configuration variables:
------------------------
- **co2** (**Required**): The CO_2 data from the sensor in parts per million (ppm).
- **name** (**Required**, string): The name for the CO_2 sensor.
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
- All other options from :ref:`Sensor <config-sensor>`.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
sensor. Defaults to ``60s``.
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
to use multiple UART buses.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for actions.
