The SparkFun Qwiic Stress Sensor options the BMP384 and excels at high-resolution measurements (as much as 21-bit). The SparkFun Qwiic Stress Sensor options the BMP384 strain sensor from Bosch Sensortec. The BMP384 excels at high-resolution measurements (as much as 24-bit) and makes use of a gel-filled cavity to offer additional resistance to liquids (water and different chemical substances). This makes it an important choice for monitoring strain close to water or in humid environments although the sensor is just not water-proof with out an sufficient integration idea.
The BMP384 gives wonderful accuracy throughout a large measurement vary (300hPa to 1250hPa and -40 to +85°C) on a footprint that makes use of the Qwiic Normal dimension (1.0in. x 1.0in.). The sensor additionally encompasses a configurable oversampling setting, a FIFO buffer for storing as much as 73 measurements, in addition to a low go filter so customers can customise the efficiency based mostly on the applying’s necessities. The Qwiic Stress Sensor communicates over I2C by default, using our useful Qwiic system so no soldering is required to attach it to the remainder of your system. Nevertheless, we nonetheless have damaged out 0.1”-spaced pins in case you favor to make use of a breadboard and likewise helps utilizing the BMP384 over SPI.
The BMP384 has three working modes: Sleep Mode, Regular Mode and Pressured Mode. Whereas in Sleep Mode the sensor is idle and consumes ~2µA. Whereas in Regular Mode, the sensor routinely cycles between measurement and standby intervals and consumes ~700µA at peak present draw throughout measurements. Pressured Mode permits direct management of measurements to wake the sensor from Sleep Mode, take a single-shot measurement, and return the system to Sleep Mode.

The SparkFun Qwiic Stress Sensor options the BMP384 and excels at high-resolution measurements (as much as 21-bit).
Provide Voltage Vary: 1.65V – 3.6V. Present Draw: 700µA – Peak whereas measuring strain. -Board Dimensions (BMP384 in inches) 1.00 x 1.00in.
3.4 µA @ 1Hz – Stress and temperature monitoring with Extremely Low Energy oversampling settings. ~2µA – Sleep Mode. Knowledge Switch Speeds: I2C – 3.4MHz, SPI – 10MHz. :I2C Handle: 0x77 (Default), 0x76 (Alternate) Inside Temperature Sensor.
The BMP384 is a high-resolution digital strain sensor from Bosch with a large measurement vary (300hPa to 1250hPa) and wonderful accuracy.
The SparkFun Qwiic Join System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping sooner and fewer vulnerable to error. All Qwiic-enabled boards use a typical 1mm pitch, 4-pin JST connector. This reduces the quantity of required PCB area, and polarized connections imply you’ll be able to’t hook it up incorrect.
