Mingjiada Electronics Supply Bosch BMP280 Sensor - Ultra-low Power Consumption High-precision Digital Barometric Pressure Sensor

Product Description Of BMP280
The BMP280 is an ultra-low-power, high-precision digital barometric pressure sensor developed by BOSCH, utilising piezoresistive pressure sensing technology. It is optimised for mobile devices, navigation systems, weather monitoring, and industrial applications. The BMP280 is an upgraded version of the BMP180, offering significant improvements in accuracy, package size, and power consumption.

The core advantage of the BMP280 lies in its miniature packaging (LGA-8, 2.0 × 2.5 × 0.95 mm) and ultra-low power consumption (operating current as low as 2.7 µA @1 Hz), making it an ideal choice for battery-powered devices. Additionally, the BMP280 supports I²C and SPI communication protocols, offering flexible interface adaptation solutions.

Product Features Of BMP280
High-Precision Measurement
The BMP280 offers an absolute accuracy of ±1 hPa (950–1050 hPa, 0–40°C) and a relative accuracy of ±0.12 hPa (equivalent to ±1 metre altitude resolution).
Built-in temperature compensation with a temperature drift coefficient of only 1.5 Pa/K ensures long-term stability.
Ultra-low power consumption design
The BMP280 consumes only 2.7 µA at a 1 Hz sampling rate, with sleep mode current as low as 0.1 µA, significantly extending device battery life.
Wide measurement range
The BMP280's barometric pressure measurement range is 300–1100 hPa (corresponding to altitudes from -500 m to +9000 m), and its temperature measurement range is -40°C to +85°C.
Environmental Adaptability
Some versions of the BMP280 feature an IPX8 waterproof rating, making them suitable for harsh environments.
Flexible Interfaces and Configuration
The BMP280 supports I²C (0x76/0x77) and SPI (three-wire/four-wire) communication, compatible with Arduino, STM32, and other microcontroller platforms.
