BMP390L is an industrial-grade dedicated digital barometric pressure sensor newly developed by Bosch. It has extremely high-temperature stability, low drift, low power consumption (sleep current is only 54μA, the highest power consumption in measurement mode is 650μA) and low noise impact (less than 0.02Pa).

The maximum deviation of the absolute accuracy of this product is less than 50Pa, and the relative accuracy can reach ±3Pa (equivalent to 25cm), which is 166.7% higher than the previous generation.

In addition, with a 12-month long-term stability deviation of only 16Pa, the new model's long-term stability performance far exceeds that of the previous generation. Accurate, stable, low-power height detection makes this product very suitable for indoor positioning applications that cannot be covered by GPS signals.

Since it offers extended availability up to 10 years, you can use this product with peace of mind.
