The MPRLS Ported Pressure Sensor Breakout is an absolute pressure measurement module designed for applications where pressure must be measured inside an enclosed space. Unlike standard barometric sensors, this module features a metal pressure port, allowing tubing to be attached directly for accurate air or gas pressure sensing.
The sensor integrates a factory-calibrated pressure sensing element with a high-resolution 24-bit ADC and temperature compensation. Communication is handled via an I2C interface, making it simple to integrate with microcontrollers and single-board computers.
This module is suitable for assistive devices, laboratory experiments, vacuum systems, and sealed container pressure monitoring.
