Description
SEN0423 is a Fermion: BMP390L digital barometric pressure sensor (Breakout). BMP390L is an industrial-grade dedicated digital barometric pressure sensor newly developed by Bosch. It features 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). With a maximum deviation of absolute accuracy of less than 50Pa and a relative accuracy of ±3Pa (equivalent to 25cm), this sensor provides 166.7% higher performance than its previous generation. Additionally, it boasts a long-term stability deviation of only 16Pa over 12 months, making it ideal for accurate, stable, and low-power height detection in indoor positioning applications not served by GPS signals.
