Structure Mini Weather Sensor
- Meteorological Sensing Module: Integrates four types of sensors—wind speed, wind direction, temperature and humidity, and atmospheric pressure—and is responsible for collecting raw environmental and meteorological data.
- Main Control PCB: Equipped with a main control chip, RS485 communication circuitry, and a voltage regulator, it performs data calibration calculations and transmits signals externally.
- Protective Housing: With a diameter of 50 mm and a height of 65 mm, it features a vented design to block dust and foreign objects and protect the internal circuitry.
- Mounting Accessories: Include two types of mounting bases—top-mount and bottom-mount—to accommodate both unmanned aerial vehicle (UAV) and conventional pole-mounting methods.
- Circuitry Accessories: Include filter components, temperature compensation devices, and terminal blocks to mitigate electromagnetic interference and ensure stable, long-term monitoring performance.
Working Principle Mini Weather Sensor
- Environmental Data Acquisition: Sensors for wind speed, wind direction, temperature, humidity, and atmospheric pressure simultaneously detect changes in the surrounding environment and collect meteorological parameters in real time.
- Multi-Sensor Fusion: The built-in processor performs simultaneous sampling, filtering, and compensation of data from each sensor to improve measurement accuracy and stability.
- Data Computation and Processing: Built-in algorithms calculate wind speed, wind direction, and environmental parameters, minimizing the effects of flight vibrations and electromagnetic interference.
- Real-Time Data Output: Processed meteorological data is transmitted in real time via communication interfaces to the UAV flight control system, data logger, or ground station.
- Flight Decision Support: The flight control platform optimizes flight attitude, flight path planning, and mission execution based on real-time meteorological data, enhancing flight safety and operational efficiency.
- Continuous Dynamic Monitoring: Meteorological data is continuously updated during UAV flight, enabling mobile, real-time environmental monitoring to meet the needs of applications such as inspection, agriculture, scientific research, and emergency monitoring.
