Bmp280 altimeter Hello! I am building an Arduino Altimeter with BMP280. Contribute to adafruit/Adafruit_BMP280_Library development by creating an account on GitHub. 3 is a high-precision sensor module designed for measuring atmospheric pressure and temperature, making it suitable for applications such as altimetry and weather monitoring. Ideal for weather stations, drones, GPS navigation, and IoT projects, it offers reliable data with low power consumption and easy integration with Arduino, Raspberry Pi, and other microcontrollers. Feb 18, 2025 · The BMP280 - 3. After uploading the code and adjusting my float level of my local hPa pressures accordingly my altitude was calibrated to my exact elevation. Build the circuit and write a sketch example. Sep 14, 2020 · Interfacing BMP280 with Arduino to Read Pressure, Temperature, and AltitudeThis article shows how to interface a BMP280 Pressure sensor with Arduino. Furthermore, it serves as an altimeter with a±1 meter accuracy. I did find two Ebay sellers of BMP280 4 pin pcb's that are direct replacements for the BMP180 4 pin pcb's.
