Product Description

BMP280 I2C Digital Barometric Pressure & Altitude Sensor Module

High-Precision Environmental Sensor for Arduino and IoT Projects

The BMP280 is a highprecision, lowpower digital barometric pressure and temperature sensor from Bosch Sensortec. It is the upgraded successor to the popular BMP180, offering superior accuracy, lower noise, and a smaller footprint [citation:1][citation:2][citation:7]. With its I2C interface and wide voltage support, it is an ideal choice for weather stations, altitude tracking, and indoor navigation projects .

High Precision Measurement - ±1 hPa pressure accuracy and ±1°C temperature accuracy for reliable environmental sensing [citation:7][citation:9].
Dual Interface Support - Operates with both I2C and SPI, with I2C as the default for simple wiring [citation:7][citation:12].
Supply Voltage: 3.3V to 5V DC, making it compatible with both 3.3V and 5V logic systems [citation:5][citation:9].
The default I2C address is often 0x76 or 0x77, depending on the SDO pin configuration [citation:6][citation:8].
