Differential Pressure Sensor MPX5010

Integrated Silicon Pressure Sensor On-Chip Signal Conditioned, Temperature Compensated and CalibratedThe MPxx5010 series piezoresistive transducers are state-of-the-art monolithic silicon pressure sensors designed for a wide range of applications, but particularly those employing a microcontroller or microprocessor with A/D inputs. This transducer combines advanced micromachining techniques, thin-film metallization, and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure. The axial port has been modified to accommodate industrial grade tubing This sensor detects changes in air pressure at its two ducted ports. The output of the sensor is an analog voltage that varies depending on the pressure. The pressure sensor can detect changes in both positive and negative air pressure. Positive air pressure is equivalent to blowing into a tube. Negative air pressure creates a vacuum, similar to sucking from a straw. Connections To connect the pressure sensors to the Arduino Shield, attach the three leads of the device as shown in the figure. The sensor is a 6-pin device, but only pins 1-3 are connected. Note that pin 1 is denoted by a small notch. Although the leads on the pressure have the standard 0.100" spacing, it is recommended that you connect the device to the Arduino using male-female jumper wires, rather than plugging the sensor directly into the breadboard of the Arduino Shield. This allows you more flexibility in connecting tubes to the sensor.
