BMP390L Digital Atmospheric Pressure Sensor Module Replaces BMP388 BME280 Low Power ConsumptionItem NO.: BMP390L

BMP390L Digital Atmospheric Pressure Sensor Module

Product Introduction:

The BMP390L is a newly developed industrial grade dedicated digital air pressure sensor with extremely high temperature stability, low drift, low power consumption (sleep current only 54uA, maximum power consumption measurement mode 650uA), and low noise impact (below 0.02Pa). The maximum 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 long-term stability performance of the new model is also far ahead of the performance of the generation, with a long-term stability error of only 16 Pa in 12 months. Accurate, stable, and low-power high detection makes this product very suitable for applications such as indoor positioning that cannot be covered by GPS signals, and the product has a delivery period of up to ten years, so it can be safely integrated into your device.
