The SENSIRION SDP3X family sensors comes with deferential pressure range of (500Pa, 125Pa) on i2c and analog in a small package. suitable for high-volume applications where size is required on a design project. The SDP3X family ideal for measuring of mass flow in a bypass configuration. This sensor is a reflow solderable, can implement a multiple sensor in a series at multiple i2c addresses and interrupt functions in a fast sampling time and offer a calibrating and temperature compensated analog voltage output and configurable different measurement speed, output curves and temperature compensation can be selected dynamically during at run-time mode. The SDP3X family sensors has integrated excellent accuracy at long-term stability and no zero-point drift suitable for medical instruments, portable medical devices, home and health care applications, environmental devices, and drones. For more technical details refer to the datasheet below.
