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.\u003cbr\u003eThe 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.\u003cbr\u003eBMP388 is based on Bosch’s mature Piezo resistive pressure sensor technology featuring high accuracy as well low power consumption and high EMC robustness.\u003cbr\u003eThe sensor features an accuracy of about ±8Pa, which is equivalent to about ±0.5m difference in altitude, and an absolute accuracy temperature of ±0.5℃ for a temperature range between 0℃ and 65℃.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLow power consumption\u003c\/li\u003e\n\u003cli\u003eLow noise\u003c\/li\u003e\n\u003cli\u003eHigh resolution\u003c\/li\u003e\n\u003cli\u003eSmall dimensions\u003c\/li\u003e\n\u003cli\u003eBest-in-class offset temperature coefficient（-20℃-65℃@700-1100hPa）\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 3.3V-5.5V\u003c\/li\u003e\n\u003cli\u003eOperating Current: 0.5mA\u003c\/li\u003e\n\u003cli\u003eOperating Range: 300-1250 hPa\u003c\/li\u003e\n\u003cli\u003eRelative Accuracy: ±8 Pa (equivalent to ±0.50m @700-900hPa, 25℃-40℃)\u003c\/li\u003e\n\u003cli\u003eAbsolute Accuracy: ±50 Pa（0℃-65℃@300-1100hPa）\u003c\/li\u003e\n\u003cli\u003eTemperature Coefficient Offset: ±0.75 Pa\/K（-20℃-65℃@700-1100hPa）\u003c\/li\u003e\n\u003cli\u003eAbsolute Accuracy Temperature: ±0.5℃（@0℃-65℃）\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40℃~80℃ (more accurate in 0℃-65℃)\u003c\/li\u003e\n\u003cli\u003eExternal Dimension: 22mm x 30mm\u003c\/li\u003e\n\u003cli\u003eMounting Hole Position: 15mm\u003c\/li\u003e\n\u003cli\u003eMounting Hole Dimension: inside diameter 3mm\/ outside diameter 6mm\u003c\/li\u003e\n\u003cli\u003eInterface: Gravity-I2C 4Pin or SPI (SPI is only used at 3.3V)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGravity：BMP388 Barometric Pressure Sensor module x1\u003c\/li\u003e\n\u003cli\u003ePH2.0-4P sensor cable x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0251\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67577821560909,"sku":"E30053-001","price":15.43,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E30053-win1.jpg?v=1791276930","url":"https:\/\/www.mlab.com.au\/products\/gravity-bmp388-barometric-pressure-sensors","provider":"MLAB","version":"1.0","type":"link"}
