SparkFun Micro Pressure Sensor – BMP384 (Qwiic)

Description

• SparkFun BMP384 Micro Pressure Sensor (Qwiic)
• High-resolution Bosch Sensortec BMP384 sensor
• Increased resistance to liquids with gel-filled cavity
• Wide measurement range: 300 hPa to 1250 hPa, -40 to +85 C
• Configurable oversampling, FIFO buffer, and low-pass filter
• Convenient Qwiic system for solder-free connections

The SparkFun BMP384 Micro Pressure Sensor (Qwiic) features a high-resolution Bosch Sensortec BMP384 pressure sensor. With its gel-filled cavity, the sensor offers increased resistance to liquids, making it suitable for monitoring pressure in humid environments or near water. However, it is not waterproof without proper integration.

The BMP384 ensures excellent accuracy across a wide measurement range (300 to 1250 hPa and -40 to +85 C) and has a small footprint, making it ideal for projects with limited space. Additional features include a configurable oversampling setting, a FIFO buffer for storing up to 73 measurements, and a low-pass filter, allowing customization based on application requirements. The Qwiic Pressure Sensor communicates via I2C, utilizing the convenient Qwiic system for solder-free connections.
