Introduction
BMP390L, an industrial-grade dedicated digital air pressure sensor developed by Bosch, has the characteristics of extremely high temperature stability, low drift, low power consumption and low noise. Its sleep current is only 54uA, the highest power consumption measurement mode is 650uA, and the noise impact is less than 0.02Pa.
The maximum error of absolute accuracy is less than 50Pa, and the relative accuracy can reach 3 Pa (equivalent to 25cm), which is 166.7% higher than that of the previous generation, ensuring the measurement accuracy.
The long-term stability of this model is far ahead of the previous generation, and the 12-month long-term stability error is only 16Pa. Its precision, stability and low power consumption make it very suitable for indoor positioning and other scenes that GPS signals can't cover, and it can be safely integrated into equipment.
