TBS ASI2C Digital Air Speed Sensor Kit

Want your autopilot to actually know how fast you’re moving through the air, instead of guessing like a dodgy satnav? The TBS ASI2C Digital Air Speed Sensor Kit gives you precision measurement with the trusted Measurement Specialties 4525DO sensor. With a 1 psi range (covering speeds up to ~100 m/s or 360 km/h), this kit delivers accurate, temperature-compensated airspeed data straight into your Pixhawk or PX4 board. Translation: no more lies from flaky analog sensors, and no more wingtip wobbles because your autopilot was “feeling lucky.”

Why You Want It

Because digital sensors don’t care about your ESC cooking the air around them. The ASI2C reads closer to real air temperature, giving your autopilot true airspeed instead of a sweaty CPU’s best guess. Add in high resolution (0.84 Pa steps at 14-bit output) and full compatibility with Pixhawk/PX4, and you’re set for stable, data-backed flight. Or you can keep trusting the analog setup you swore was “good enough.”
