To efficiently perform sprinkle without waste corresponding to conditions on the surface of a road by providing a liquid sprinkler with a sprinkle controller for controlling the amount of sprinkle from a sprinkle nozzle based on a detected road surface temperature from a temperature detector for detecting the temperature on the surface of the road.
A road surface temperature detector 10 is loaded on the liquid sprinkler, and the detected road surface temperature detected by this road surface temperature detector 10 is inputted to a comparator part 11 as a detecting signal. That comparator part 11 compares the detected road surface temperature with a set road surface temperature previously set by a road surface temperature setting part 12 and stored in a storage part 13 and judges the presence/absence of sprinkle. A flag for the presence/absence of sprinkle is set as the judged result and based on that flag, the amount of sprinkle is operated by an arithmetic part 14. A liquid sprinkle pump 4 is driven by a driving part 17 so as to execute sprinkle corresponding to that operated sprinkle amount. Thus, one-man work for a worker to perform sprinkle by himself can be dealt with.
