BMP390L low power digital atmospheric pressure sensor module can replace the BMP388

Product Introduction  

BMP390L is a newly developed industrial-grade digital pressure sensor developed by Bosch, which has the characteristics of extremely high temperature stability, low drift, low power consumption (sleep current is only 54uA, the highest power consumption measurement mode is 650uA) and low noise impact (less than 0.02Pa). The maximum error 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, ensuring the accuracy of the measurement. In addition, the new model also far exceeds the performance of the previous generation in long-term stability, with a long-term stability error of only 16Pa for 12 months. Accurate, stable and low-power height detection makes this product very suitable for indoor positioning and other applications where GPS signals cannot cover, and the product has a supply period of up to ten years, so it can be safely integrated into your device.
