Seeed Studio Studio Grove High Precision Barometer Sensor (DPS310) - I2C/SPI Interface

The module is designed for use with both 3.3V and 5V logic systems via its Grove connector. The onboard voltage regulator and level shifting circuitry allow safe and direct connection to common development boards like Arduino Uno (5V) or Raspberry Pi (3.3V) without external components.

Yes, the DPS310 sensor supports both I2C and SPI communication protocols. The Grove connector provides I2C access. For SPI, you must bypass the Grove connector and wire directly to the module's 6-pin SPI header, carefully following the pinout for Chip Select (CS), Serial Clock (SCLK), Master Out Slave In (MOSI), and Master In Slave Out (MISO) lines.

The sensor provides highly precise pressure data (±0.06 hPa relative accuracy), which can be converted to altitude using the barometric formula. The relative altitude accuracy is approximately ±0.5 meters under stable atmospheric conditions. For absolute altitude, accuracy is ±8 meters, as it depends on a known reference SEA-level pressure.

Absolutely. With an operating temperature range of -40°C to +85°C and a robust pressure sensing range of 300–1200 hPa, the DPS310 is well-suited for outdoor environmental monitoring. Its high precision and stability make it ideal for tracking atmospheric pressure changes for weather prediction in micro-weather stations.
