2. Professional testing technology and equipment

1. ?Automatic field microclimate observation instrument?

• Monitoring elements: wind speed, wind direction, temperature and humidity, rainfall, light, soil temperature and humidity, etc.

• Data collection: Real time transmission to the database through meteorological sensors, supporting field research applications4.

2. ?Atmospheric environment detection device (Anhui Peak Detection Technology)?

• Function: Integrated wind speed sensor, wind direction sensor, rainfall sensor, and solar power supply system.

• Application: Automated monitoring of outdoor wind speed, direction, and rainfall7.

3. ?Reference for Cleanroom Testing Standards?

• Wind speed detection method: Prioritize the use of electric anemometers (thermoelectric anemometers) instead of traditional hot ball instruments1112.

III. Key Testing Standards and Specifications

1. ?Wind speed limit?

• Outdoor: There is currently no clear limit, but the wind speed level (such as ≤ 3, 4-5) needs to be marked for traffic meteorology9.

• Indoor: ≤ 0.3m/s in summer, ≤ 0.2m/s in winter (according to GB/T 18883-2022)11.

2. ?Temperature and humidity control range?

• Summer humidity: 40%~80%, winter: 30%~60%11.

• Airflow impact: Abnormal wind speed may cause discomfort to the human body and increase the risk of disease11.

Summary

• ?real-time dataThere are significant differences in temperature, humidity, and wind speed among major cities in Anhui Province, with high temperatures accompanied by strong southeast winds in Hefei, Fuyang, and other areas during summer18.

• ?technical supportAutomated detection equipment (such as field observation instruments and sensors) is widely used in the fields of meteorology, agriculture, and environmental monitoring47.

• ?standard basisOutdoor monitoring relies on professional equipment, and indoor environments must comply with strict limits on wind speed and humidity in GB/T 18883-2022
