The airspeed meter measures the airspeed dynamic pressure and the atmospheric static pressure at the altitude where it is located. The pressure signal is converted into an electrical signal in the differential pressure sensor, processed by an amplifier circuit, and then converted into a digital signal by the A/D to be converted into airspeed.
I²C digital airspeed meter, using TE’s MS4525DO sensor, with full calibration and temperature compensation, the total error band (TEB) is less than 1% compensation of the pressure range, the output of the I²C digital interface, with very low current consumption. Resistant to high noise interference, suitable for a variety of small fixed-wing aircraft.
