BMP280 Temperature+Pressure Sensor

The bmp280 sensor platform allows you to use your BMP280 (datasheet, Adafruit) temperature and pressure sensors with ESPHome. The I²C is required to be set up in your configuration for this sensor to work.

BMP280 Temperature and Pressure Sensor.

# Example configuration entry
sensor:
  - platform: bmp280
    temperature:
      name: "Outside Temperature"
      oversampling: 16x
    pressure:
      name: "Outside Pressure"
    address: 0x77
    update_interval: 60s

Configuration variables:

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

    • name (Required, string): The name for the temperature sensor.

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

    • id (Optional, ID): Set the ID of this sensor for use in lambdas.

    • All other options from Sensor.

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

    • name (Required, string): The name for the pressure sensor.

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

    • id (Optional, ID): Set the ID of this sensor for use in lambdas.

    • All other options from Sensor.

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

  • iir_filter (Optional): Set up an Infinite Impulse Response filter to increase accuracy. One of OFF, 2x, 4x, 16x. Defaults to OFF.

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

Pins on the BMP280. Only VCC, GND, SCL, and SDA need to be connected.

Oversampling Options

By default, the BMP280 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)
