Couldn't load pickup availability
Suitable for Barometric Pressure, Altitude, Temperature Measuring
Supports Raspberry Pi / Raspberry Pi Pico / Arduino / ESP32 ...
TheBMP390 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, and audible devices, suitable for applications such as accurate altimeter, environment monitoring, and IoT projects.
- 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)
