4 of the 12 features in our table differ between the BME280 and the BMP280.
±1 hPa · 300 to 1,100 hPa · I²C/SPI · 1.71 to 3.6 V
Temperature, humidity and pressure in one I²C or SPI chip: the classic weather-station sensor.
Watch out: ±1 °C and ±3 %RH, less accurate than a dedicated humidity sensor. Check the chip: the BMP280 looks almost the same and has no humidity sensor.
±1 hPa · 300 to 1,100 hPa · I²C/SPI · 1.71 to 3.6 V
Bosch’s barometer: ±1 hPa absolute, ±0.12 hPa relative (about ±1 m of altitude), 2.8 µA at one reading a second.
Watch out: Bosch recommends the BMP390 for new designs. No humidity, and 1.71 to 3.6 V only: on 5 V, use a board with a regulator.
| Feature | BME280 | BMP280 |
|---|---|---|
| Measures | temperature · humidity · pressure | pressure · temperature |
| Current at 1 reading/s | 3.6 µA | 2.8 µA |
| ESPHome | bme280_i2c / bme280_spi | bmp280_i2c / bmp280_spi |
| Status | Available | End of life |
Same on both: absolute accuracy · relative accuracy · pressure range · temperature accuracy · interface · I²C address · supply · current between readings.
In our table the BMP280 has nothing the BME280 lacks, and it is at the end of its life: choose it only for price or a board you already have.

The BME280 offers humidity as well as temperature, a part still in production, and a ready-made configuration in this site’s ESPHome generator; in our table the BMP280 has no advantage of its own apart from price, and it is at the end of its life.
Absolute accuracy, for weather readings: ±1 hPa for the BME280, ±1 hPa for the BMP280. Relative accuracy, for altitude: ±0.12 hPa and ±0.12 hPa.
Often yes: both use I²C or SPI. Change the driver or, in ESPHome, the component (bme280_i2c → bmp280_i2c).
