BMP390 barometric pressure sensor, I2C/SPI interface, low noise, for drone, GPS and portable devices, altitude and temperature measurement.

Discover our BME390 environmental sensor module, a versatile and precise solution for your measurement projects. This module is equipped with a high-performance BMP390 sensor and is ready to use thanks to its integrated level switching circuit, compatible with 3.3V and 5V voltages. **Main Features:** * **Flexible Communication Interface:** It supports communication via I2C and SPI interfaces. By default, it is configured to use the I2C interface. * **Multiple Measurements:** This unique module is capable of accurately measuring barometric pressure, ambient temperature, and calculating altitude. * **High Accuracy and Low Noise:** Enjoy reliable measurement with very low noise. It offers an absolute pressure accuracy of ±0.50 hPa and a remarkable relative accuracy of ±0.03 hPa in specific ranges. The supported resolution can reach 0.016 Pa in high-precision mode.

* **Compact and Energy Efficient:** Its small size and very low power consumption (average operating current of 3.2μA at 1Hz) make it perfect for portable or battery-powered applications.

* **Wide Operating Range:** Operates over a pressure range of 300 to 1250 hPa and supports temperatures from -40°C to +85°C.
