BMP390L Arduino Precision Air Pressure and High Meter Temperature Sensor Pressure Module

Product introduction:

BMP390L is an industrial-grade dedicated digital pressure sensor with extremely high temperature stability, low drift, low power consumption (sleep current only 54uA, measurement mode maximum power consumption 650uA) and low noise impact (below 0.02pA). The maximum 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 measurement accuracy. In addition, the new model is also ahead of the previous generation in terms of long-term stability performance, with a long-term stability error of only 16PA for 12 months. High-precision, stable and low power consumption make this product ideal for indoor applications that cannot be covered by GPS signals. In addition, the product has a supply period of up to ten years, so it can be safely integrated into your equipment.

Application scenarios:

Vertical speed indication (eg, rising/sinking speed),
GPS navigation enhancement (eg, improving the starting positioning time, dead recall, slope detection),
indoor navigation and positioning (indoor detection, elevator detection),
outdoor navigation, leisure and sports applications,
weather forecasting
, health care equipment applications (eg, key capacity measurement),
fitness applications. (such as enhanced calorie detection)
Augmented reality and virtual reality applications
Situation awareness
Industrial Internet of Things equipment
