Digital AirSpeed Sensor Kit TBS ASI2C
Featuring a Measurement Specialties 4525DO sensor, with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h), the TBS ASI2C Digital Air Speed Sensor Kit enables a resolution of 0.84 Pa, with data delivered at 14 bits from a 24 bit delta-sigma ADC. It also measures temperature to allow calculation of true airspeed from indicated airspeed using the MS5611 static pressure sensor on Pixhawk. Not influenced by the heat of nearby processing components, it is much closer to the air temperature than with previous analog sensor setups. Supported on all Pixhawk and PX4 autopilot generation boards, this kit comes with M3/6-32 mounting holes.
Features:
- Temperature Sensing: Integrated temperature measurement enables true airspeed (TAS) calculation when used with a static pressure sensor (e.g. MS5611 on Pixhawk)
- Anti-heat design: Shielded from heat generated by nearby electronics to ensure reliable temperature readings
