Relação do Módulo I2c Spi do Sensor de Pressão Atmosférica da Elevada Precisão Bmp390 Compatível com Arduino e Stm32

Product Introduction

BMP390 is a very small, low power, low noise, 24 bit atmospheric pressure sensor. High-performance digital sensors are ideal for all kinds of height sensing, indoor positioning and floor level detection, enhanced GPS for outdoor navigation, indoor navigation, accurate fitness tracking and calorie consumption estimation. This new BMP390 pressure sensor has excellent design flexibility, allowing customers to easily integrate it into many existing and upcoming devices, such as smartphones, GPS modules, wearables, auditory devices and drones.

Accurate, stable and compact

BMP390 has a typical relative accuracy of + 0.03hPa, which is better than any other comparable product on the market today. Typical accuracy is + 0.5hPa. Excellent accuracy is the result of significant improvements in temperature stability, drift behavior and noise. The sensor is high-temperature stable over the entire operating temperature and over the entire pressure range of 0 to 65? and 700 to 1100hPa, with an average temperature coefficient deviation (TCO) of only ±0.6Pa/K. The noise is also very low. Typically only 0.9Pa, a 25% reduction from the previous BMP380. The device also has high stability.
