The Adafruit BMP390L is a high-precision barometric pressure and altitude sensor that is ideal for a variety of applications, including environmental measurements and altitude stabilization in drones and quadcopters. With improved accuracy compared to its predecessors, the BMP280 and BMP388, the BMP390L offers a relative accuracy of ±3 Pascal, which corresponds to an altitude deviation of only ±0.25 meters. The sensor supports both I2C and SPI interfaces, allowing for flexible integration into various projects. Its fast conversion time and low altitude noise make it an excellent choice for projects requiring precise altitude measurements. The BMP390L is not only suitable for aviation applications but can also be used in wearable devices and other applications that require accurate measurements of altitude above sea level.
