BMP280 Temperature+Pressure Sensor
The bmp280 sensor platform allows you to use your BMP280
(datasheet
,
Adafruit_) temperature and pressure sensors with ESPHome. The I²C or SPI is
required to be set up in your configuration for this sensor to work.
# Example configuration entry I2C
sensor:
- platform: bmp280_i2c
temperature:
name: "Outside Temperature"
oversampling: 16x
pressure:
name: "Outside Pressure"
address: 0x77
update_interval: 60s
# Example configuration entry SPI
sensor:
- platform: bmp280_spi
temperature:
name: "Outside Temperature"
oversampling: 16x
pressure:
name: "Outside Pressure"
cs_pin: GPIO5
update_interval: 60sConfiguration 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 pressure sensor. See Oversampling Options.
- All other options from Sensor.
iir_filter (Optional): Set up an Infinite Impulse Response filter to increase accuracy. One of
OFF,2x,4x,16x. Defaults toOFF.update_interval (Optional, Time): The interval to check the sensor. Defaults to
60s.
I²C Configuration variables:
- address (Optional, int): Manually specify the I²C address of
the sensor. Defaults to
0x77. Another address can be0x76.
SPI Configuration variables:
- cs_pin (Optional, Pin Schema): The CS pin of the BMP280 sensor.
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)1x2x4x8x16x(default)
