  • Description

The SparkFun Qwiic MicroPressure Sensor is a miniature breakout equipped with Honeywell's 25psi piezoresistive silicon pressure sensor.

This MicroPressure Sensor offers a calibrated and compensated 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.
