Since the beginning of the period (June 1st - August 22nd), the precipitation in Hebei Province is 10% more than normal, but the distribution is uneven, showing the characteristics of less northwestern part of the northeast; the temperature is higher than normal; the local area is short Strong convective weather such as strong precipitation, thunderstorms and strong weather and a large range of heavy rainfall have caused some meteorological disasters and caused certain economic losses and casualties.
1. The precipitation in Hebei Province is 10% higher than that in normal years, and the distribution is less in the northwest.
Since entering Yunnan, the province's average rainfall is 341.7 mm, and the average rainfall is 34.9 mm (11.4%) more than the average of 30 years (306.8 mm), which is more than 10%. The rainfall is unevenly distributed. The maximum rainfall is 630.6 mm, and the Shangyi is only 131.3 mm. The larger rainfall area mainly appears in the northeast and middle (Fig. 1). From the perspective of precipitation distribution, the overall characteristics of the northeast and the northwest are relatively small. The average values ​​of Chengde, Tangshan, Qinhuangdao, Langfang and Baoding are 19%-26% in the same period of the past 30 years, and more than 8 in Zhangzhou, Shijiazhuang and Xingtai. %-11%, Hengshui, 邯郸 close to normal years, Zhangjiakou is less than 9%.
2. Since the temperature is higher than normal, the average temperature in the province is 26.3 °C, which is 1.2 °C higher than the average of the past 30 years (25.1 °C).
3. Since the introduction of meteorological disasters, strong convective weather such as short-term heavy rainfall, thunderstorms and strong weather, and a large range of heavy rainfall have caused a certain meteorological disaster, mainly as local flash floods, farmland water, Urban hustle, wind and lightning.
According to incomplete statistics of relevant departments, since the enrollment, there have been 6.838 million people affected by meteorological disasters in Hebei Province, 5762 people with emergency resettlement, 19 people died due to disasters, 12 people were injured, 2 people were missing (including 9 people killed by lightning strikes, heavy rain) 3 people died in mountain torrents, 2 people were missing, 1 person died in thunderstorm and gale, 6 people died from surface collapse caused by rainfall. The area affected by crops was 335.3 thousand hectares, the area covered by 19.5 thousand hectares, 2476 houses collapsed, and 17410 houses were damaged, resulting in direct economy. The loss was 2.83 billion yuan.

LED Sensor Batten Lights has options of microwave sensor and infrared sensor. There are two sensing modes. One is 0-10v dimming, and the other is on/off.
The main difference between these two modes is that the 0-10v dimming mode can set the brightness of the light after the person walks, and the pending time of this brightness can also be set. On/off mode, you can only set the time for the lights to turn off after a person walks, but not the brightness (that is, functions 3, 4 cannot be implemented). The 0-10v dimming mode is more intelligent.
Briefly introduce the function of sensor light:
1. Set up daylight threshold: If the ambient light is higher than the set brightness, the sensing function will not be triggered.
2. Set up the hold time: The time for the light to maintain brightness after the person walks away.
3. Set up a stand-by dim level: set the brightness maintained after the person walks
4. Set up stand-by time: After the person walks, the time to maintain low brightness
5. Set up detection area: Set the detection area.
Toggle button can set the remote distance of remote control and sensor.
If you need sensor lights in factories or warehouses, corridors, or other indoors, you can choose this LED Sensor batten lights. If you need IP66 sensor light, you can choose Sensor Waterproof Light.
