A new smart sprinkler offers solar power for easier lawn care.
The Oto Smart Sprinkler measures 16 x 12 x 4 inches and weighs about 6 pounds. It requires at least three hours of direct sunlight daily to charge its 5,400-mAh battery via a 2.2-watt solar panel. Users can cover up to 5,000 square feet with water thrown as far as 40 feet in a 360-degree radius.
