BME680 Temperature+Pressure+Humidity+Gas Sensor

The bme680 sensor platform allows you to use your BME680 (datasheet, Adafruit) temperature, pressure and humidity sensors with ESPHome. The I²C is required to be set up in your configuration for this sensor to work.

BME680 Temperature, Pressure & Humidity Sensor.

# Example configuration entry
sensor:
  - platform: bme680
    temperature:
      name: "BME680 Temperature"
      oversampling: 16x
    pressure:
      name: "BME680 Pressure"
    humidity:
      name: "BME680 Humidity"
    gas_resistance:
      name: "BME680 Gas Resistance"
    address: 0x77
    update_interval: 60s

Configuration variables:

  • temperature (Optional): The information for the temperature sensor.

    • oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options.

    • All other options from Sensor.

  • pressure (Optional): The information for the pressure sensor.

    • oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options.

    • All other options from Sensor.

  • humidity (Optional): The information for the humidity sensor.

    • oversampling (Optional): The oversampling parameter for the temperature sensor. See Oversampling Options.

    • All other options from Sensor.

  • gas_resistance (Optional): The information for the gas sensor.

  • address (Optional, int): Manually specify the I²C address of the sensor. Defaults to 0x76. Another address can be 0x77.

  • iir_filter (Optional): Set up an Infinite Impulse Response filter to increase accuracy. One of OFF, 1x, 3x, 7x, 15x, 31x, 63x and 127x. Defaults to OFF.

  • heater (Optional): The settings for the internal heater for the gas sensor. Set this to disable the internal heater.

    • temperature (Optional, int): The target temperature of the heater between 200 and 400 °C. Defaults to 320.

    • duration (Optional, Time): The duration the heater should be active. Maximum value is 4032ms. Defaults to 150ms.

  • update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.

Oversampling Options

By default, the BME680 sensor measures each value 16 times when requesting a new value. You can, however, configure this amount. Possible oversampling values:

  • NONE (value is skipped)

  • 1x

  • 2x

  • 4x

  • 8x

  • 16x (default)

Advanced Configuration

Add indoor air quality (IAQ) calculation and IAQ label, based on the values in the BME680 BSEC component index.
