Grove - High precision barometric pressure sensor (DPS310)
An advanced barometer that measures pressure and temperature with high accuracy (ideal for various applications). With a pressure data resolution of 0.06 Pa RMS (or 0.01 m), a pressure sensor accuracy of ± 0.002 hPa (or ± 0.02 m) and a relative accuracy of ± 0.06 hPa (or ± 0.5 m), it is probably one of the best barometric pressure sensors.
Grove's high-precision barometric pressure sensor is based on the latest DPS310 from Infineon . The DPS310 is a miniaturized digital barometric pressure sensor with high accuracy and low power consumption that can measure both pressure and temperature. The pressure measurement range of this sensor is between 300 and 1200 hPa and the temperature measurement range is between -40 and 85 °C. Therefore, you can use it to measure air pressure, altitude and temperature and build your own Arduino barometer. This sensor is not only very accurate, but also extremely easy to use. You can flexibly choose between the integrated Grove IIC interface or the 6-pin SPI interface. When it comes to the Grove IIC connector, you can simply connect it to the Seeeduino or Arduino+ base shield, no wiring, no soldering required, and it works for both 3.3V/5V systems. All in all, it's a time- and money-saving high-precision Arduino air pressure sensor solution.
