Bosch Sensortec developed the BMP280 as a barometric pressure sensor. It’s designed with high accuracy and precision to measure atmospheric pressure and temperature. The sensor is commonly used in various applications such as weather stations, altitude measurement, indoor navigation, and IoT (Internet of Things) devices.
The BMP280 sensor utilizes a MEMS (Micro-Electro-Mechanical Systems) pressure sensor to detect atmospheric pressure changes. Additionally, an integrated temperature sensor provides temperature measurements. These measurements enable the calculation of altitude and provide data for weather forecasting, environmental monitoring, and other applications.
This sensor communicates with microcontrollers or other devices via standard interfaces like I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface). Consequently, it’s easy to integrate into a wide range of electronic systems.
