Want to have a very accurate reading of your APM airspeed?, then look no further than the APM Digital Airspeed Sensor which is supplied with its own pitot tube. This MPXV7002DP Air Speed Sensor And Pitot Tube Set for APM must be used in conjunction with the APM PX4 autopilot system.
This unit has a very high resolution, low offset digital pressure sensor which enables it to register extremely accurate airspeed readings. This sensor does not suffer from noise caused by long cables or from offsets caused by ratio-metric outputs which older analog airspeed systems suffer from.
The Measurement Specialities 4525DO sensor is capable of measuring speeds of up to 100m/s (223mph/360kmh) using a 0.84 Pa with data delivered at 14 bits from a 24 bit delta-sigma ADC.
This airspeed sensor also has a built-in temperature sensor to allow the calculation of true airspeed from the indicated airspeed using the MS5611 static pressure sensor on the APM PX4. If you are flying multi-copters then you do not require this unit as it is only usable if you are using the fixed-wing code in the APM.
This patented, single element 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 MPXV7002 is designed to measure positive and negative pressure. In addition, with an offset specifically at 2.5V instead of the conventional 0V, this new series allows to measure pressure up to 7kPa through each port for pressure sensing but also for vacuum sensing (refer to the transfer function in the data sheet for more detailed information).
The upper tube is dynamic (measuring the air pressure of front opening, air is compressed into airspeed tube), the bottom tube is static (measuring the side port airspeed tube). When you install airspeed sensor with multi-copter, using this airspeed tube combo. The combo includes two tubes, one dynamic tube one static tube
Airspeed does some help with heavy wind, slow speed flying and automatic landing.
