BMP388 Barometric Pressure Sensor
User Manual
OVERVIEW
This is a 24-bit high precision barometric pressure sensor, which allows accurate
altitude tracing, as well as barometric pressure / temperature measuring. It supports
both I2C and SPI interfaces, also is compatible with 3.3V/5V voltage levels.
Due to its ultra-small form factor, low power consumption, low noise and high
precision, the BMP388 Barometric Pressure Sensor is suited for applications such as
drones, accurate altimeter, environment monitoring, and IoT projects, and so on.
