Pressure sensors are used in a wide range of applications. You can find them in the medical field (blood pressure monitoring, negative pressure wound therapy), they have industrial uses (air braking systems, gas and water meters), and have a wide range of consumer uses (coffee machines, humidifiers, air beds, washing machines, dishwashers). Measuring in at 1 square inch, the SparkFun Qwiic MicroPressure Sensor takes advantage of HoneyWell's MPR Series piezoresistive silicone pressure sensor and our plug-and-play Qwiic System to make pressure measurement easy and portable.

The MPRLS0025PA00001A boasts a small form factor (5 mm x 5 mm), easy to read 24 bit digital I2C output, and is 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). Add to that ultra-low power consumption (as low as 0.01 mW typ. average power, 1 Hz measurement frequency) and Qwiic ports, you've got yourself a power packed little sensor!
