RAIN SENSOR: The irrigation computer is equipped with a rain sensor on the top. When it rains, the watering program stops automatically. Once the water on the chip has evaporated or dried out naturally, the watering schedule will automatically resume. This feature can be turned on or off. Multiple Modes: The automatic watering schedule has a child lock mode that prevents children and pets from triggering the watering schedule, preventing thereby damaging plants and wasting water. Manual mode can be selected for temporary watering when the temperature is high. WATERPROOF: The drip irrigator can be used outdoors because the exterior of our garden irrigator is made of waterproof ABS plastic + PC, suitable for 0.05-0.8Mpa water pressure and outdoor conditions. 1/2 and 3/4 tap connections. Wide range of applications: sprinkler irrigation systems do not generate pressure. The automatic water timer can be used for tap watering or compressed watering.
