The HK Pilot32 digital differential airspeed sensor is the next generation of sensors, it uses digital data instead of an analog voltage signal. Analog signals are subject to induction and noise problems, especially in longer wires. Causing error and false data, the new Digital airspeed indicator fixes all of these issues.

Featuring a high resolution Measurement Specialties 4525DO sensor, with 1 psi measurement range. The HK Pilot32 Airspeed Sensor Kit enables a resolution of 0.84 Pa, with data delivered at 14 bits from a 24 bit delta-sigma ADC, bottom line it's accurate and fast! It also measures true air temperature to allow the HK pilot to better compare data with the on-board sensors for a true airspeed indicator. Supported on all HK pilot32, Pixhawk and PX4 autopilot generation boards, this kit comes with M3 / 6-32 mounting holes.

Included:
Digital Air Speed Sensor x 1
4pin cable x 1 (155mm)
Rubber tubing x 1 (300mm)
Pitot tube x 1 (86mm)
