Adafruit BMP388 precision barometer, air pressure meter + temperature sensor The BMP388 sensor board from Adafruit has the successor to the tried and tested BMP180 or. BMP280 from Bosch. The BMP388 sensor module delivers higher precision than its predecessor and can be configured via I2C and SPI. The relative measuring accuracy of the sensor is 8 Pa, which corresponds approximately to a height difference of ± 0.5 m. The temperature can be determined with an accuracy of ± 0.5 ° C. Ideal for e.g. drones and quadrocopters to be able to maintain the altitude or any other application that requires the precise measurement of altitude. The breakout board can be operated with 3.3 V and 5 V and has the necessary level converters. More hints and a tutorial on how to use it with Arduino can be found.
