Overview of Drone Pressure Sensor Applications

Application Scenario Core Function Key Technology/Advantage Problem Solved
Flight Altitude Control & Navigation Measures atmospheric pressure data, converted via calculation to altitude (altimeter). Enables precise altitude locking and autonomous takeoff/landing. Provides stable altitude reference in absence or inaccuracy of GPS signal (e.g., indoors, canyons), preventing drift.
Motor/Propeller Status Monitoring Monitors air pressure from motor cooling systems or airflow generated by propellers. Real-time diagnosis of system health status. Early warning for motor overheating, propeller damage, or efficiency loss, preventing flight incidents.
Airspeed Management Measures the drone's relative speed to air (airspeed) via a pitot tube. Maintains stable flight speed and attitude in windy conditions. Relying solely on ground speed (GPS speed) can cause stall in headwinds or excessive speed in tailwinds; airspeed management ensures flight efficiency and safety.
Fuel/Energy Management Monitors gas pressure within fuel cells or tanks. Optimizes energy usage efficiency and accurately estimates endurance. Ensures stable operation of the energy system, avoiding loss of control due to energy depletion, especially critical for industrial long-endurance drones.
Ground Station Weather Monitoring Functions as part of a portable weather station, providing precise local barometric data. Real-time meteorological data collection and forecasting. Provides critical on-site meteorological information for takeoff decisions and route planning, ensuring flight safety.
