Product description
BMP280 – pressure and temperature sensor with SPI/I2C
The BMP280 is a precision sensor from Bosch that measures both temperature and barometric pressure. It can also be used as an altimeter with ±1 metre accuracy. The module communicates via I2C or SPI and includes a built-in 3.3V regulator and logic level shifter, making it compatible with both 3.3V and 5V systems. Suitable for weather monitoring, altitude sensing and environmental applications. Arduino libraries and example code are available.
