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.

|
|
|
|
|
|
|
|
|
- **co2** (**Required**): The CO_2 data from the sensor in parts per million (ppm).
|
|
|
|
|
|
|
|
|
|
- **name** (**Required**, string): The name for the CO_2 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

|
|
|
|
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for actions.
