Honeywell MPR Series MicroPressure Board Mount Pressure Sensors
Product Overview
The Honeywell MPR Series is a compact, highly accurate piezoresistive silicon pressure sensor designed for a wide range of medical, commercial appliance, and industrial/HVAC applications. Offering a digital I2C or SPI output, these sensors are calibrated and compensated for offset, sensitivity, temperature effects, and non-linearity via an on-board ASIC, simplifying integration and reducing manufacturing costs. Their very small form factor, wide pressure ranges, and enhanced performance through direct microprocessor interface make them a value-driven solution for higher volume needs. The series is IoT-ready and available with various pressure types and ranges.
