DISTRIBUTION LIST

1 * BMP388 air Pressure Sensor
1 * Ocean interface JST 6-Pin Cable
This is a high-precision digital air pressure sensor, integrated with BMP388 chip to achieve data tracking accurately, Monitor atmospheric pressure and temperature, support I2C/SPI interface, and compatible with 3.3V/5v voltage.It compatible with Raspberry/Arduino/STM32 and other motherboards.
The BMP388 digital pressure sensor is a very compact 24-bit sensor with low power consumption and low noise. The sensor offers a best-in-class temperature coefficient offset (TCO) between 0 Degree Celsius and 65 Degree Celsius for accurate height measurement over a wide temperature range. The digital sensor has low power consumption, only 3.4μA at 1Hz, and a wide measurement range from 300hPa to 1250hPa.
for flying toys, drones, handheld devices, such as mobile phones, tablets, GPS devices, navigation systems, portable health devices, home weather stations, watches, white goods and other application scenarios.
Note: The altitude calculated by the air pressure sensor is generally used as a relative value in a short period. For example, when taking a vertical elevator, record a height before the elevator starts, and the elevator rises to the 3rd floor, and records a height. The height difference between the two heights is accurate.
If you need to use it in absolute situations, you can enter the height of the current position as the initial value of the calculation, and then exercise to observe the height change is accurate. However, if the time is long, the problem of height drift will easily occur. If the project requires long-term acquisition of accurate altitude values ​​and high frequency requirements, it needs to integrate other sensors for processing, such as GPS.
