Claims

[Scope of Claim for Utility Model Registration] (1) A timer that opens the water supply valve of a watering pipe connected to a watering nozzle for a predetermined period of time, a light sensor that detects the surrounding brightness, and a light sensor that detects the surrounding brightness until the surrounding brightness reaches a predetermined brightness. and control means for operating the timer when the timer is activated. (2) A timer that opens the water supply valve of the watering pipe connected to the watering nozzle for a predetermined period of time, a light sensor that detects ambient brightness, a rain sensor that detects rainfall, and a timer that opens the water supply valve of the watering pipe connected to the watering nozzle, and a rain sensor that detects rainfall until the surrounding area reaches a predetermined brightness. 2. A water sprinkling device characterized by comprising: a control means that operates the timer when the timer is activated, and closes the water supply valve when rainfall is detected by the rain sensor while the timer is operating. (3) A timer that opens the water supply valve of the watering pipe connected to the watering nozzle for a predetermined period of time, a light sensor that detects ambient brightness, a temperature sensor that detects the ambient temperature, and a rainfall sensor, When the brightness of the temperature sensor reaches the brightness of A water sprinkling device comprising: a control means for closing the water supply valve when the water supply valve is detected. (4) The watering device according to claim 1, 2 or 3, wherein the control means determines whether the detected value from the optical sensor reaches at least one of morning and evening brightness.
