Waveshare BMP388 High Precision Barometric Pressure Sensor Accurate Altitude Tracing Temperature Measuring I2C SPI Interface Suited for Drones Altimeter Environment Monitoring and IoT Projects

Description

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. Features Supports I2C (default) / SPI interface Onboard voltage level translator, compatible with 3.3V/5V operating voltage Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32) Specifications Operating voltage: 3.3V/5V Communication interface: I2C/SPI Barometric pressure operation range: 300~1250hPa Barometric pressure absolute accuracy: ±0.40hPa (@900~1100hPa, 25~40℃) Barometric pressure relative accuracy: ±0.08hPa (@900~1100hPa, 25~40℃) Temperature coefficient offset: ±0.75Pa/K (@700~1100hPa, -20~65℃)） Temperature absolute accuracy: ±0.5℃ (0~65℃） Possible resolution: 0.016Pa (high precision mode) Possible sampling rate: 200Hz Operating voltage: -40~85℃ Dimension: 32mm × 20mm Mounting hole size: 2.0mm PACKAGE CONTENT BMP388 Barometric Pressure Sensor x1 PH2.0 5PIN wire x1Development Resources Wiki : www.waveshare.com/wiki/BMP388_Barometric_Pressure_Sensor
