Waveshare BMP388 24-Bit High Precision Barometric Pressure Sensor, Accurate Altitude Tracing, I2C

A 24-bit measurement resolution gives this sensor finer gradations in its pressure readings than a lower-resolution chip manages, which matters directly for altitude tracing - more bits of pressure resolution translate into smoother, less stair-stepped altitude estimates rather than readings that jump between coarse increments. Alongside the BMP390 already in the catalogue, this BMP388 gives a choice of barometric sensor within the same broad family, letting a project pick whichever specific chip's exact characteristics best fit its altitude-tracking accuracy needs.
