BMP390 High Precision Barometric Pressure Sensor, Barometric Pressure / Altitude / Temperature Measuring

BMP390 High Precision, Barometric Pressure Sensor , Suitable for Barometric Pressure, Altitude, Temperature Measuring, Supports Raspberry Pi / Raspberry Pi Pico / Arduino / ESP32 ...

The BMP390 is a 24-bit absolute barometric pressure sensor, with the features of ultra-small form factor, low power consumption and low noise. This digital high-performance sensor is ideal for a variety of altitude tracking applications. Supports both I2C / SPI interfaces, compatible with 3.3V/5V voltage levels. It can be easily integrated into projects such as GPS modules, wearables devices, audible devices and drones, suitable for applications such as accurate altimeter, environment monitoring, and IoT projects.

Features At A Glance

  • Onboard BMP390 sensor for measuring barometric pressure, altitude and temperature
  • Supports I2C communication, I2C address configurable, with I2C bus cascading support
  • Supports SPI communication, enabled via CS pin (I2C bus by default)
  • Onboard voltage translator, compatible with 3.3V/5V level
  • Comes with online development resources and manual (examples for Raspberry Pi / Raspberry Pi Pico / Arduino / ESP32)
