Smart sprinklers only water your lawn when it’s thirsty
Putting your sprinklers on a timer system is probably the best way to avoid under-watering your plants — but the “set and forget” mentality isn’t the most economical. What if it rains during the week and you forget to turn the timer off? Now you’re wasting water and drowning your lawn. A company called ETwater thinks it has a better automatic solution: a smart sprinkler that only waters your lawn when it actually needs it.
