Bosch BMP390 Barometric Pressure Sensor

Bosch Sensortec BMP390 Barometric Pressure Sensor is designed to provide pressure and temperature measurement that is based on proven sensing principles. This sensor operates from 1.65V to 3.6V main supply voltage range (VDD) and 300hPa to 1250hPa pressure range at 0°C to 65°C temperature range. The BMP390 sensor features low power consumption of 3.2µA at 1Hz (typical) to maximize battery life in portable device applications. This sensor is available in 2.0mm x 2.0mm x 0.75mm dimensions and is ideal for use in smartphones and wearable/hearable devices. Typical applications include the Internet of Things (IoT), weather forecast, context awareness, vertical velocity indication, AR/VR applications, health care, and enhancement of GPS navigation.
