The BMP280 is a digital barometric pressure and temperature sensor designed for applications that require atmospheric pressure measurement along with temperature data.
Because atmospheric pressure changes with altitude, pressure measurements from the BMP280 can be used by a microcontroller to estimate changes in elevation or relative altitude when an appropriate reference pressure and calculation method are used.
The sensor supports common digital communication interfaces, making it suitable for integration with microcontrollers and development boards in electronics and STEM projects.
Typical applications include weather monitoring, environmental data logging, altitude experiments, IoT projects, barometric measurement and experimental flight-related projects.
The BMP280 is particularly useful for demonstrating how atmospheric pressure can be converted into meaningful environmental information through sensor interfacing and software calculations.
