Mouser now stocks the BMP388 digital barometric pressure sensor from Bosch. Highlighting a best-in-class temperature coefficient offset (TCO) between 20C and 65C, the small, low-power, low-noise sensor provides accurate altitude measurement over a broad temperature range. The sensor employs proven sensing principles to produce pressure and temperature measurements. The 24-bit device covers a measurement range of 300hPa to 1250hPa while consuming just 3.4µA at 1Hz. The sensor features a raw interrupt functionality for easy access to storage and data, while a built-in IIR filter minimises short-term disturbances like those caused by slamming doors or windows. This digital barometric pressure sensor is housed in a 10-pin, 2mm × 2mm × 0.75mm LGA metal-lid package and offers FIFO functionality that decreases power consumption while enhancing ease of use. The compact device is perfect for altitude stabilisation in consumer drones, IoT applications, healthcare applications, vertical velocity indication, weather forecasting, AR and VR devices, and enhanced GPS accuracy.
