Once it enters a low-temperature, rainy, or high-humidity environment, the air inlet of the pipe body can easily freeze quickly and be blocked by frost. When the air inlet passage is completely blocked, the UAV's airspeed data is lost directly, speed measurement fails, and the flight control judgment is disordered, which can easily lead to yaw, crash, and flight accidents. The risk is extremely high in inspection, emergency rescue, and high-altitude operation scenarios.
Rain-proof and de-icing pitot tubes are used for UAV airspeed collection. It is suitable for situations where rain and frost caused by UAV operations in rainy and snowy weather, high-cold and high-altitude environments block the airspeed tube, making it impossible to collect UAV total pressure and airspeed data. equippedHigh-precision automatic temperature control module starts intelligent heating as soon as power is turned on, providing real-time resistancefrost condensationKnot，When the temperature reaches the standard, it automatically enters the constant temperature mode. It does not freeze at low temperatures and does not block the holes in rainy days. It ensures smooth air intake channels all day long and the airspeed acquisition is stable and accurate throughout the process.
Two installation methods to choose from

Specifications:
Pay attention to the positive and negative poles of the power supply. Red is the positive pole and black is the ground. 0.5A current when powered by 26V.
The indicator light of the heating module lights up after power is turned on, goes out when the temperature is reached, and lights up and off slowly in the constant temperature state.
It can be customized to add heating status feedback. The signal is an open-drain mode output I/O, and the user needs to connect a pull-up resistor for use.
Notice:
1: When the pitot tube is powered on, avoid touching the pitot tube with your hands to avoid burns.
2: Do not turn on the heating function when the dust cap is covered.
3: When transporting, please try to put the dust cap back on to prevent sediment and dirt from entering the pitot tube.
4: When installing the machine, install the drainage holes downward and cannot be blocked.
5: Do not pull the cable vigorously at any time to avoid damage.
6: Prevent the positive and negative poles of the power supply and the heating wire sensor wire from being damaged and short-circuited.
