The device consists of a host, an electric ball valve, a pyroelectric body sensor, or an infrared sensor. There are two sets of timing controllers inside the host computer: one set of timers for human body induction stop spray timing , which realizes the function of stopping spraying when people come and recovering the spray when people go; the other set is a microcomputer time controller and realizes time division. Automatic spray function by cycle. Its principle: First, when someone passes, the sensor receives the signal, the host processes the signal, so that the electric ball valve stops the spray, the spray resumes when the person leaves; Second, according to the dust content in the roadway, the user determines the length of the spray time and spray cycle , to achieve a period of periodic spray dedusting .
