Water scarcity is one of the most pressing problems in the world right now. According to the World Wildlife Fund (WWF), 70% of our planet is covered by water. However, only 3% of it is fresh water, and only one-third of that is available for consumption. Many water systems are stressed due to the growing human population and over-consumption. Agriculture consumes more water than any other source. Much of the water used in agriculture is wasted due to inefficient irrigation systems. To alleviate this problem, many governments impose restrictions on water usage, especially in drought-stricken states like California. However, these bans are difficult to enforce. For example, some people can afford to violate the restrictions and simply pay the fines. To improve irrigation efficiency and properly enforce water usage restrictions, this starter kit is a prototype for a smarter, connected sprinkler system.
