CJMCU-390 BMP390L BMP390 Precision Barometric Pressure and Altimeter Sensor Digital Atmospheric Pressure Sensor Replaces BMP388 and BME280 for Arduino

Introduction:1：The new generation of pressure sensor bmp390 can provide unparalleled accuracy for height tracking in smart phones and wearable and ear wearable devices. 2：Thanks to the improved resolution, the new bmp390 can measure height changes below 10 cm, and the accuracy is 50% higher than that of the previous generation of sensors. 3：Accurate height detection can achieve positioning function in the room where GPS signal cannot cover. 4：By adding a vertical specific position to the existing horizontal information, the first responder can determine the floor of the smartphone user triggering the emergency call.Futures：1:The typical relative accuracy of bmp390 is + / - 0.03 HPA； 2： the typical absolute accuracy can reach + / - 0.5 HPA. Its excellent accuracy is due to the significant improvement in temperature stability, drift behavior and noise reduction；3：The sensor operates at full operating temperature (0 to 65 ℃) ° C) ；4：The average temperature coefficient shift (TCO) is only + / - 0.6 PA / K；5：In addition, the noise is also very low, only 0.9 PA, which is 25% lower than the previous generation bmp380；6：The device also has high long-term stability and low short-term and long-term drift

• CJMCU-390 BMP390L Digital atmospheric pressure sensor replaces BMP388 and BME280 for Arduino
• This sensor has a relative accuracy of ±3 Pascals, which translates to about ±0.25 meters of altitude (compare to the BMP280's ±12 Pascal/±1 meter and BMP388's ±8 Pascal/±0.5 meter).
• The BMP390L has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations.
• Its excellent accuracy is attributed to the significant improvement in temperature stability, drift behavior and noise reduction.
• The new bmp390 can measure height changes below 10 cm, and the accuracy is 50% higher than the previous generation of sensors.
