The Virtualrain line of rain sensors provides the user with the most effective and flexible way to prevent sprinklers from coming on during or after precipitation.

Disks absorb water and expand proportionally to the amount of rainfall. The moistureladen disks expand and eventually activate a switch that interrupts the circuit from the controller to the valves. When dry, the disks contract and release the switch. There’s no better way to ensure that a system isn’t watering. Virtualrain offers four different models to provide the user with the most cost effective way to reduce water waste. The wireless model offers the added value of saving installation time. Simply install the receiver unit next to the controller, and then install the transmitter anywhere that the device can receive representative rainfall. No ladders needed, no messy wires to hide out of view. What sets a Virtualrain wireless rain sensor apart is a solar cell that continually recharges the transmitter batteries.
