An aluminium alloy is adequate.
If you are talking about the little rod that melts causing the sprinkler to spray water, it is not an element. It is either a metal alloy or plastic that melts at a relatively low temperature. The older sprinklers all used metal alloy, but as the usual alloy contained lead as one of the metals that alloy has been phased out due to concern over toxicity. Where metal alloy is still used it has been reformulated without lead. But the preference now is to use plastic rods.The image above shows a sprinkler with red colored plastic rod.
Sprinklers that do not need melting to activate are called "fusible link sprinklers." Instead of relying on heat to melt a fusible link, these sprinklers have a heat-sensitive element that responds to a certain temperature, causing the sprinkler to activate and release water.
The element that makes up the majority of the human body is oxygen.
Oxygen is the element that makes up 78% of air and belongs to the 15th group in the periodic table.
The element with the symbol N is nitrogen. It is a non-metallic element that makes up about 78% of the Earth's atmosphere.

Overhead sprinklers for irrigation are inefficient primarily due to evaporation and wind drift, which can result in significant water loss before it reaches the ground. Additionally, they often lead to uneven water distribution and may overwater some areas while leaving others dry. This inefficiency can increase water waste and reduce the overall effectiveness of irrigation efforts.
John Deere does not make lawn sprinklers. They have a division where they sell landscape and irrigation parts. You can find their site at: http://www.johndeerelandscapes.com
Overhead sprinklers are often inefficient due to their tendency to distribute water unevenly, leading to both overwatering in some areas and under-watering in others. Additionally, factors like wind can cause water to drift away from the intended target, resulting in wastage. They also tend to create evaporation losses, especially during hot weather, further reducing their effectiveness in delivering water to plants.
element makes those TVs
Irrigation sprinklers are the most common on farms.
The company that makes the least expensive overhead projector is Nobo Quantum. Their projectors start at $150 and go up to $500. Their products can be bought on their website.
This element is cobalt.
Sprinklers in a factory remove heat from the fire triangle.
Grocery stores have sprinklers only above the produce section because, when it is time to, the sprinklers automatically turn on according to how dry and products are. Hoped this helped! :)
