BME280

The BME280 is a digital sensor that measures atmospheric pressure, temperature, and humidity. It is manufactured by Bosch Sensortec and is widely used in various electronic projects and commercial products. The sensor communicates using either the I2C or SPI serial interfaces, making it compatible with a wide range of microcontrollers such as Arduino, Raspberry Pi, and ESP32.

The BME280's capabilities include measuring pressure with an absolute accuracy of ±1.0 hPa across a range of 300 to 1100 hPa. Its temperature sensing range is from -40 to +85 degrees Celsius with a typical accuracy of ±1.0°C. The humidity sensor operates within a range of 0 to 100% relative humidity, providing an accuracy of ±3%. These specifications allow the BME280 to be employed in applications like weather stations, altitude estimation, indoor navigation, and personal health monitoring.

The compact size and low power consumption of the BME280 make it suitable for battery-powered devices and portable electronics. Its integrated digital signal processing and calibration data ensure reliable and accurate readings. The sensor is often found integrated into modules that simplify its connection and use for hobbyists and engineers alike.
