the mobile carrier 1 can be of various kinds: 1. existing electric vehicles and fuel-consuming vehicles; 2. a human-powered towing vehicle; 3. unmanned aerial vehicles, etc.

A humidity sensor for detecting the environmental humidity is arranged on the mobile carrier 1, the humidity sensor is coupled with the processor 6 and is provided with a humidity threshold range;

when the environmental humidity is lower than the humidity threshold range, the processor 6 controls the water spraying device 2 to spray water according to the first water quantity signal;

when the environmental humidity is within the humidity threshold range, the processor 6 controls the water spraying device 2 to spray water according to the average water quantity signal;

when the ambient humidity is higher than the humidity threshold range, the processor 6 controls the water spraying device 2 to spray water according to the second water amount signal.

The design of the invention is as follows: in the motion process of the moving carrier 1, the detector 4 continuously detects the density of objects to be sprinkled at the position below the moving carrier 1, the preferred design position of the detector 4 is in front of the moving carrier, the enhancing detector 4 is matched with the sprinkling device 2, and firstly, the light emitter 41 emits induction light (the induction light can be laser light or infrared light) to cause two conditions: 1. the object to be sprinkled in front, the sensing light is reflected by the object to be sprinkled and reflected back to the first light receiver 42; 2. without the object to be sprinkled in front, the sensing light passes directly into the second light receiver 43. The processor 6 generates a reflected light intensity curve according to the intensity of the reflected sensing light received by the first light receiver 42, and when the intensity of the reflected sensing light is stronger, the density of the object to be sprinkled is higher;

the processor 6 generates a penetration light intensity curve according to the intensity of the penetration sensing light received by the second light receiver 43, and the intensity of the penetration sensing light is weaker while the intensity of the object to be sprinkled is higher.

In addition, the humidity sensor is designed, for example, in the early morning or after rain, when the humidity of the environment is too high, a layer of water drops or a water film may be formed on the surface of the object to be sprinkled, which causes a decrease in the light reflectivity, and greatly affects the accuracy of the first light receiver 42, so that the second light receiver 43 is used as the reference when the humidity is too high. When humidity is moderate, the average water quantity signal is used as the standard, when humidity is too low, the environment is too dry, external dust is too large, external illumination influence is too large, and long-distance light irradiation influence is too large, so that the first light receiver 42 with a short distance is used as the standard.
