2. Field Engineering Operations (Industrial Commercial)

Power / Wind Turbine Inspection, Communication Tower Construction: High-altitude Work Wind Speed Safety Threshold Judgment (Stop Work in Strong Wind) Construction scaffolding and tower crane outdoor construction: Real-time measurement of wind gusts to avoid risks of falling objects and overturning.

Geological exploration, forestry patrol, waterway surveying: Field-based meteorological data recording.

3. Firefighting, emergency rescue

Forest firefighting, mountain search and rescue: Monitoring wind speed, temperature and humidity around the fire site to predict the direction of fire spread; Calculating heat index in high-temperature environments to prevent rescue personnel from suffering heat stroke.

4. Agriculture, forestry, agricultural planting

Farm, orchard, greenhouse, pest control drone operations: Monitoring wind speed when spraying pesticides to avoid pesticide drift; Recording field temperature, humidity and dew point to assist crop management.

5. Education, research, meteorological observation

Geographical meteorological experiments in primary and secondary schools, university field environment research; Simple meteorological inspections in small parks and scenic areas; Outdoor study tours, summer camp environment safety monitoring.

6. Security, blasting operations

Open-pit mines, engineering blasting sites: Monitoring wind speed and direction (only wind speed values), controlling the range of dust dispersion from blasting.
