▶ Product Introduction

YIGU Sensor YGY-QXY Handheld Meteorological Instrument

(5-Parameter Portable Weather Station)

The YIGU Sensor YGY-QXY Handheld Meteorological Instrument is a portable, easy-to-operate weather station that integrates five essential meteorological parameters into a single compact device: wind speed, wind direction, temperature, humidity, and atmospheric pressure.

Equipped with high-precision sensors and an intelligent processing chip, the instrument delivers accurate real-time measurements with reliable data logging. The built-in mechanical wind vane, combined with an automatic north-pointing mechanism, enables intuitive reading of wind direction across 16 compass points — simply align the vane and read directly on the integrated compass dial.

For data storage, the YGY-QXY features a large-capacity FLASH memory chip capable of holding up to one year's worth of meteorological records (up to 38,000 data entries). Data can be easily exported to a PC via the standard USB port and accompanying meteorological software, allowing users to perform in-depth analysis, generate reports, and archive historical data.

The instrument's low-power design ensures extended field operation, while the 128×64 large LCD screen provides clear, real-time display of all measured parameters. All components are housed in a durable enclosure and come in a custom aluminum carry case for secure transport and storage.

The YIGU Sensor YGY-QXY is widely applicable across meteorology, environmental protection, aviation, agriculture and forestry, hydrology, military operations, warehousing and logistics, and scientific research — making it an ideal choice for professionals who require reliable, on-the-go meteorological data collection.

▶ Wind force (wind speed) scale

Level	Name	Characteristics of Land Surface Objects	Wind Speed (m/s)
0	Calm	Still, smoke rises vertically	0～0.2
1	Light Air	Smoke shows wind direction, leaves shake slightly	0.3～1.5
2	Light Breeze	Face feels wind, leaves move slightly	1.6～3.3
3	Gentle Breeze	Leaves and small branches keep shaking, flags unfold, tall grass keeps swaying	3.4～5.4
4	Moderate Breeze	Can blow up dust and paper on the ground, branches shake, tall grass undulates like waves	5.5～7.9
5	Fresh Breeze	Small trees with leaves sway, small waves on inland water surfaces, tall grass undulates obviously	8.0～10.7
6	Strong Breeze	Large branches shake, wires hum, difficult to hold an umbrella, tall grass sometimes lies on the ground	10.8～13.8
7	Moderate Gale	Whole trees shake, large branches bend down, difficult to walk against the wind	13.9～17.1
8	Fresh Gale	Can break small branches, great resistance when walking against the wind	17.2～20.7
9	Strong Gale	Straw houses are damaged, roof tiles are lifted, large branches can be broken	20.8～24.4
10	Storm	Trees can be blown down, general buildings are damaged	24.5～28.4
