Product overview
The makeflyeasy MFE I2C Airspeed Meter is an airspeed sensing component intended for a variety of small fixed-wing aircraft. Its sensing architecture uses a TE MS4525DO differential pressure sensor to turn pressure into an electrical signal, followed by amplification and analog-to-digital conversion to derive airspeed. The meter measures dynamic pressure and atmospheric static pressure at its location. It incorporates full calibration and temperature compensation, with an I²C digital output and resistance to high noise interference.
For installation planning, the meter measures 27.5× 19.6×15.1 mm and weighs 10.8g. Its electrical integration requirements include a 5V input, I²C communication and a GH1.25-AWB interface. The specified pressure range is 20 psi, while the airspeed measuring range is 520 km/h. Measurement accuracy is stated as 0.25% / 1% TEB, and the temperature range is -25℃～105℃. These dimensions, mass, electrical requirements and measurement limits define the component’s principal integration parameters for a small fixed-wing aircraft.
