As shown in the figure below, when the height changes in centimeter-level, the barometer reading inside the mobile phone has almost no change, and the output of the Grove DSP310 changes significantly.   

What is called “high precision”? That is high precision!!! 

Features

• High Pressure Precision: ± 0.002 hPa (or ±0.02 m)
• High Pressure Accuracy: ± 0.06 hPa (or ±0.5 m)-Relative; ± 1 hPa (or ±8 m)-Absolute
• Wide Range: Pressure: 300 –1200 hPa; Temperature: -40 – 85 °C.
• Easy to Use: Grove IIC (with interrupt) / SPI
• Low power consumption

We can’t wait to introduce you to this marvelous Barometer Sensor! With 0.06 Pa_RMS (or 0.01m) pressure data resolution, ± 0.002 hPa (or ±0.02 m) pressure sensor precision and ± 0.06 hPa (or ±0.5 m) relative accuracy, it’s probably one of the best barometric pressure sensors, incredibly, it only costs $ 5.9!

The Grove – High Precision Barometric Pressure Sensor is based on Infineon latest DPS310. The DPS310 is a miniaturized Digital Barometric Air Pressure Sensor with high accuracy and low current consumption, capable of measuring both pressure and temperature. The pressure measurement range of this sensor is 300 -1200 hPa, and the temperature measurement range is -40-85 ° C. Therefore you can use it to measure the air pressure, altitude, temperature, and build your own Arduino barometer.

This sensor is not only highly accurate but also extremely easy to use. You can flexibly choose the onboard Grove IIC interface or 6-pin SPI interface. When it comes to Grove IIC port, you can just plug it into the Seeeduino or Arduino+baseshiled, no wiring, no soldering required, and works for both 3.3V/5V system. All in all, it’s a time and money saving high precision Arduino barometric pressure sensor solution, don’t miss it.
