The SparkFun Qwiic MicroPressure Sensor is a miniature breakout equipped with Honeywell's MPR Series piezoresistive silicon pressure sensor. This MicroPressure Sensor offers a wide pressure sensing range of 60mbar to 2.5bar, easy to read 24 bit digital I2C output, and can be calibrated and compensated over a specific temperature range for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). With its ultra-low power consumption and Qwiic ports, you've got yourself a power packed little sensor!
Each Qwiic MicroPressure Sensor has a calibrated pressure sensing range from 1-25psi and a power consumption rate as low as 0.01mW typ. average power, 1Hz measurement frequency for ultimate portability. Used in multiple medical (blood pressure monitoring, negative pressure wound therapy), industrial (air braking systems, gas and water meters), and consumer uses (coffee machines, humidifiers, air beds, washing machines, dishwashers), the SparkFun Qwiic MicroPressure Sensor is a great addition to the SparkFun Qwiic ecosystem!
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.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
