Bosch BMP388 Digital Barometric Pressure Sensor
Bosch Sensortec BMP388 Digital Barometric Pressure Sensor is a very small, low-power and a low-noise 24-bit sensor housed in an extremely compact 10-pin metal-lid LGA package. This absolute barometric pressure sensor performs pressure and temperature measurements based on the proven sensing principles. The BMP388 sensor offers outstanding design flexibility and is specifically designed to suit a wide range of altitude tracking applications. This sensor exhibits best-in-class Temperature Coefficient Offset (TCO) between 0°~65°C for accurate altitude measurement over a wide temperature range. This digital sensor consumes 3.4µA at 1Hz low power and covers a wide measurement range from 300hPa to 1250hPa.
