Description:The BMP388 digital pressure sensor is a very small, low power and low noise 24-bit sensor, this absolute pressure sensor is based on proven sensing principles for pressure and temperature measurement. The BMP388 sensor offers excellent design flexibility and is specifically designed for a variety of height tracking applications. The sensor has the best-in-class temperature coefficient offset (TC0) between 0 C and 65 C for accurate height measurements over a wide temperature range. The digital sensor has a low power consumption of 3.4uA at 1Hz and a wide measurement range from 300hPa to 1250hPao that can be used in a wide range of fields such as drones, mobile phones, tablets, GPS devices, portable medical devices, home weather stations, watches, large household appliances and more.Features:Working voltage :DC1.7 to 3.6V Relative accuracy: typical value 8pa is equal to 0.50m(700900hpa, 2540℃)Current consumption: 3.4uA at 1 Hz for pressure and temperature, 2.0uA in sleep modeOperating temperature :-40℃+85CDetection range :3001250hpaCommunication interface :12C(up to 3.4MHz)/SPI(3-wire or 4-wire, up to 10MHz)Pins definition:VIN: Power positive3Vo:3V output terminalGND: groundSCK:12C/SPI serial clock cableSD0:12C address selection bit4-wire SP1 mode data output terminal SDl:12C serial data cable 4-wire SPI mode Data input terminal 3-wire mode Input/output terminal CS: SPI starts communication in low power hours, SPI stops in high power hourscommunicationINT: Interrupt pinWhen the module is in 12C mode, SD0 can be used to select the 12C device address of the module. When SD0 is the 7-bit 12C device address of the module is 1110110(0x76) in low normal times, and when SD0 is the 7-bit 12C device address of the module is 1110111(0x77) in high normal times.High precisionHigh long-term stabilityExtremely high temperature stability and low drift characteristicsLow power consumptionApplications:Vertical speed indication (e.g. rise/sink speed)GPS navigation enhancements (e.g. improved initial positioning time, dead reckoning, slope detection)Indoor navigation and positioning (indoor detection, elevator detection) Outdoor navigation, leisure and sports applicationsWeather forecastHealth care applications (e.g., spirometry) Fitness applications (e.g., enhanced calorie detection)Augmented reality and virtual reality applicationsSituational awarenessIndustrial iot devices
