SparkFun Pressure Sensor - BMP384 - Qwiic Environmental Sensor - BMP384 Digital Pressure Sensor

The SparkFun Qwiic Pressure Sensor features the BMP384 and excels at high-resolution measurements (up to 21-bit). The SparkFun Qwiic Pressure Sensor features the BMP384 pressure sensor from Bosch Sensortec. The BMP384 excels at high-resolution measurements (up to 24-bit) and uses a gel-filled cavity to provide extra resistance to liquids (water and other chemicals). This makes it a great option for monitoring pressure near water or in humid environments though the sensor is not water-proof without an adequate integration concept. The BMP384 provides excellent accuracy across a wide measurement range (300hPa to 1250hPa and -40 to +85°C) on a footprint that uses the Qwiic Standard size (1.0in. x 1.0in.). The sensor also features a configurable oversampling setting, a FIFO buffer for storing up to 73 measurements, as well as a low pass filter so users can customize the performance based on the application's requirements. The Qwiic Pressure Sensor communicates over I2C by default, utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1”-spaced pins in case you prefer to use a breadboard and also supports using the BMP384 over SPI. The BMP384 has three operating modes: Sleep Mode, Normal Mode and Forced Mode. While in Sleep Mode the sensor is idle and consumes ~2µA. While in Normal Mode, the sensor automatically cycles between measurement and standby periods and consumes ~700µA at peak current draw during measurements. Forced Mode allows direct control of measurements to wake the sensor from Sleep Mode, take a single-shot measurement, and return the device to Sleep Mode.

• ✅ Supply Voltage Range: 1.65V - 3.6V. Current Draw: 700µA - Peak while measuring pressure. -Board Dimensions (BMP384 in inches) 1.00 x 1.00in.
• ✅ 3.4 µA @ 1Hz - Pressure and temperature monitoring with Ultra Low Power oversampling settings. ~2µA - Sleep Mode. Data Transfer Speeds: I2C - 3.4MHz, SPI - 10MHz. :I2C Address: 0x77 (Default), 0x76 (Alternate) Internal Temperature Sensor.
• ✅ The BMP384 is a high-resolution digital pressure sensor from Bosch with a wide measurement range (300hPa to 1250hPa) and excellent accuracy.
• ✅ The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
