  • Detects Soil Moisture   Wireless Communication   Battery Operated   Save on Water Bill

    The Melnor Aqua Sentry works with select Melnor AquaTimer automated hose timers (sold separately) to prevent over-watering. The AquaSentry is an advanced moisture detector transmitter that should be placed in the general watering area and will send a wireless signal back to the AquaTimer via the included wireless receiver. The transmitter is powered via 2 AA batteries, so it is truly a wireless device. Before the timer waters, the moisture in the soil will be checked via the AquaSentry. If no water is needed, the watering cycle will be skipped - assuring healthier plants and beautiful lawns, while conserving precious resources. If the required moisture level is achieved during he watering cycle, the timer will be stopped to prevent over-watering. This is the ideal solution for those without a green thumb, those looking to save natural resources and those looking to save a little on their water bill. It is especially handy for living in drought ridden areas were water conservation is of utmost importance.
