Gravity BMP388 barometric pressure sensors. It is equipped with the functionality of temperature and pressure measurement. It supports Arduino code control. Compared with the earlier version of BMP180, BMP280 and BMP388, this sensor exhibits lower power consumption, higher resolution and higher sampling rate. The barometric pressure is usually used to measure barometric pressure and temperature. But besides that, we can also use the sensor to measure the altitude and the relative floor height due to the fact that there is a certain relationship between altitude and barometric pressure. What’s more, BMP388 enables accurate GPS tracking. So with an IMU sensor and BMP388, we can experience 3D indoor positioning and navigation.

• Low power consumption, low noise, high resolution
• Best-in-class offset temperature coefficient（-20℃ to -65℃ at 700-1100hPa）
• 3.3V-5.5V operating voltage, 0.5mA operating current and 300-1250hPa operating range
• Relative accuracy: ±8Pa (equivalent to ±0.50m at 700-900hPa, 25℃ to -40℃)
• Temperature coefficient offset: ±0.75 Pa/K（-20℃ to -65℃ at 700-1100hPa）
• Mounting hole position: 15mm
• Mounting hole dimension: inside diameter 3mm/ outside diameter 6mm
• Interface: gravity-I2C 4Pin or SPI (SPI is only used at 3.3V)
