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.
