BMP280 Digital Barometric Pressure Sensor Module

If you loved the old BMP180, you are going to fall for Bosch Sensortec next-gen BMP280. This little 26-bit sensor combines lab-quality barometric measurement accuracy with a digital temperature sensor in one tiny, encapsulated package, providing a simple I²C or SPI output interface. Attached to a thoughtfully designed breakout board with a 3.3 V regulator and level-shifting logic, the BMP280 plugs directly into 5 V Arduinos, ESP32 boards, STM32 Nucleo boards, Raspberry Pi, and even 1.8 V microcontrollers — no solder-jumpers or voltage math necessary.

Why choose BMP280?

Trust in the power of absolute accuracy. This equates to approximately ±1 m in altitude (depending on the local environmental conditions) making them perfect for drone hover stabilisation, balloon or even mountaineering watch telemetry with a typical ±0.12 hPa pressure sensor.

• 26-bit resolution. You can feel the updown variation of merely 0.01 hPa(≈ 10 cm in height) when you open a windows or get upto a chair.
• Adaptive Oversampling & Filter. There are four different oversampling modes and an on-chip finite impulse response filter that allow you to sacrifice conversion time (2.3 ms → 34 ms) for stable digits, eliminating wind-gust noise without additional code.
• Dual-bus support. Got bunched up I²C bus with daisy chaining sensors? Use 4-wire SPI transfers at 10 MHz that have no address conflict.
• Sips power. The BMP280 consumes ~2.7 µA in normal-mode; in sleep it drops below 1 µA which is perfect for coin-cell loggers or solar powered LoRa nodes:

Real-world applications

• Drone flight controllers: combine high-rate pressure data with IMU outputs for the smoothest altitude hold ever.
• Internet of Things weather stations: Growing especially cool are these logbook-style local pressure trend loggers that let you detect stormy weather hours ahead of time.
• Intelligent heating and cooling: Adjust energy consumption based on the monitored internal pressure.
• Wearables & sports tech: Give hikers, cyclists and snowboarders real-time elevation gain without the GPS battery drain,
• STEM Tasks: Determine lapse rates, test the barometric equation, or create your very own radio-sonde.

Effortless integration

There are plenty of open-source libraries: Adafruit_BMP280, SparkFun BMP280, Bosch BMP2-API to name a few, so you will have mindful °C, hPa and m readings on your serial monitor in no time. Hook-up is four-wire (VIN, GND, SCL/CLK, SDA/MOSI), plus two just toggle SPI (CSB, SDO) and set the I²C address (0x76 / 0x77) for multi-sensor rigs. It comes with straight headers unsoldered, so you can mount flat, vertical or on flying leads in a 3D-printed case.
