T6613/15 CO2 Sensors ================================== .. seo:: :description: Instructions for setting up T6613 and T6615 sensors for ESPHome :image: t6615.jpg :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. .. figure:: images/t6615.png :align: center :width: 50.0% T6615 CO_2 Sensor. .. _amphenol: https://amphenol-sensors.com/en/telaire/co2/525-co2-sensor-modules/319-t6615 As the communication is done using UART, you need to have an :ref:`UART bus ` 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. .. code-block:: yaml # Example configuration entry sensor: - platform: t6615 co2: name: CO2 Configuration variables: ------------------------ - **co2** (**Required**): The CO_2 data from the sensor in parts per million (ppm). All options from :ref:`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 ` if you want to use multiple UART buses. - **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for actions. .. figure:: images/t6615-pins.png :align: center :width: 80.0% Pins on the T6615. Only the ones marked with a red circle need to be connected. See Also -------- - :ref:`sensor-filters` - `UART Protocol Documentation `__ - :apiref:`t6615/t6615.h` - :ghedit:`Edit`
