—Product Introduction BMP388 is a newly developed industrial-grade digital pressure sensor developed by Bosch, with extremely high temperature stability, low drift, low power consumption (sleep current is only 54uA, high power consumption measurement mode is 650uA) and low noise impact (less than 0.02Pa). The absolute accuracy error 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 measurement. In addition, the new model also far exceeds the performance of the previous generation in long-term stability, and the long-term stability error of 12 months is only 16Pa. Accurate, stable and low-power high-altitude 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.
